Apache Hadoop YARN is the modern distributed operating system for big data applications. It morphed the Hadoop compute layer to be a common resource management platform that can host a wide variety of applications. Many organizations leverage YARN in building their applications on top of Hadoop without themselves repeatedly worrying about resource management, isolation, multi-tenancy issues, etc. In this talk, we’ll start with the current status of Apache Hadoop YARN—how it is used today in deployments large and small. We'll then move on to the exciting present and future of YARN—features that are further strengthening YARN as the first class resource management platform for data centers running enterprise Hadoop. We’ll discuss the current status as well as the future promise of features and initiatives like: powerful container placement, global scheduling, support for machine learning and deep learning workloads through GPU and FPGA support, extreme scale with YARN federation, containerized apps on YARN, support for long-running services (alongside applications) natively without any changes, seamless application upgrades, powerful scheduling features like application priorities, intra-queue preemption across applications, and operational enhancements including insights through Timeline Service V2, a new web UI, and better queue management.

Hadoop Operations - Past, Present, and Future
Hadoop operations started on-prem primarily driven by Apache Ambari. However, due to the agility and flexibility of the cloud, it has driven many Hadoop cluster operations to the cloud and to hybrid environments. Cloud is enabling many ephemeral on-demand use cases which is a game-changing opportunity for analytic workloads. But all of this comes with the challenges of running enterprise workloads in the cloud securely and with ease.
Apache Ambari is used by thousands of Hadoop Operators to manage the deployment, lifecycle, and automation of DevOps for Hadoop ecosystem projects. Starting out, Apache Ambari installed a handful of Apache Hadoop ecosystem projects, on a few operating systems, and helped with the most basic Hadoop operational tasks. Today, the product manages over 20 different services, runs on multiple major operating systems and versions, and automates many of the most challenging Hadoop operational tasks in the most secure customer environments.
In this session, we will also take you through Cloudbreak as a solution to simplify provisioning and managing enterprise workloads while providing an open and common experience for deploying workloads across clouds. We will discuss the challenges (and opportunities) to run enterprise workloads in the cloud and will go through a live demo of how the latest from Cloudbreak enables enterprises to easily and securely run Apache Hadoop. This includes deep-dive discussion on Ambari Blueprints, recipes, custom images, and enabling Kerberos -- which are all key capabilities for Enterprise deployments.
As part of this talk, will walk you through what we've learned, the challenges we've overcome, and how the Apache Ambari and Cloudbreak community has changed the product to handle them. The future is fast approaching, and with it comes new on-premise and cloud deployment architectures. See how Apache Ambari and Cloudbreak are being re-imagined to handle these new challenges.
Apache Hadoop YARN: state of the union - Tokyo
Apache Hadoop YARN is the latest distributed operating system for HDSF for big data applications and storage. YARN has transformed the Hadoop Compute Layer into a general resource management platform capable of hosting a wide variety of applications.
This lecture begins with the current state how Apache Hadoop YARN is currently used in large scale deployment. The next topic will cover about strengthening YARN 's current and future - like YARN' s excitement - as a top-notch resource management platform for data centers running enterprise Hadoop. Discuss the current state and future of the following functions and initiatives: support of machine learning through strong container placement, global scheduling, GPU and FPGA support and deep learning workload, large scale of YARN federation, on YARN Containerized applications, natural support that does not change to long-running services (along with applications), seamless application upgrades, powerful scheduling functions, operational improvements and better queue management.
The second part of the lecture focuses on the latest enhancement of HDFS. HDFS has several advantages: horizontal scale of IO bandwidth, storage scaled to petabyte storage. In addition, it provides extremely low latency metadata operations and coordinates for over 60,000 concurrent clients. Hadoop 3.0 recently introduced Erasure Coding. One limitation of HDFS is the scaling of multiple files and blocks in the system. I will explain the fundamental change of Hadoop's storage infrastructure using Ozone technology which will be announced soon. This will allow Hadoop to scale billions of files and blocks in the future to a larger number of smaller objects than before.
The First Mile – Edge and IoT Data Collection with Apache NiFi and MiNiFi
Apache NiFi MiNiFi allows data collection in brand new environments — sensors with tiny footprints, distributed systems with intermittent or restricted bandwidth, and even disposable or ephemeral hardware. Not only can this data be prioritized and have some initial analysis performed at the edge, it can be encrypted and secured immediately.
Abstract: Apache NiFi provided a revolutionary data flow management system with a broad range of integrations with existing data production, consumption, and analysis ecosystems, all covered with robust data delivery and provenance infrastructure. Now learn about the follow-on project which expands the reach of NiFi to the edge, Apache MiNiFi. MiNiFi is a lightweight application which can be deployed on hardware orders of magnitude smaller and less powerful than the existing standard data collection platforms. With both a JVM compatible and native agent, MiNiFi allows data collection in brand new environments — sensors with tiny footprints, distributed systems with intermittent or restricted bandwidth, and even disposable or ephemeral hardware. Not only can this data be prioritized and have some initial analysis performed at the edge, it can be encrypted and secured immediately. Local governance and regulatory policies can be applied across geopolitical boundaries to conform with legal requirements. And all of this configuration can be done from central command & control using an existing NiFi with the trusted and stable UI data flow managers already love.
Expected prior knowledge / intended audience: developers and data flow managers should have a passing knowledge of Apache NiFi as a platform for routing, transforming, and delivering data through systems (a brief overview will be provided). The talk will focus on extending the data collection, routing, provenance, and governance capabilities of NiFi to IoT/edge integration via MiNiFi.
Takeaways: Attendees will learn about opportunities to bring their data flow and capture closer to the "edge" -- sources of data like IoT devices, vehicles, machinery, etc. They will understand the possibilities to prioritize, filter, secure, and manipulate this data earlier in the data lifecycle to enhance their data visibility and performance.

Ozone and HDFS’s evolution
HDFS has several strengths: horizontally scale its IO bandwidth and scale its storage to petabytes of storage. Further, it provides very low latency metadata operations and scales to over 60K concurrent clients. Hadoop 3.0 recently added Erasure Coding. One of HDFS’s limitations is scaling a number of files and blocks in the system. We describe a radical change to Hadoop’s storage infrastructure with the upcoming Ozone technology. It allows Hadoop to scale to tens of billions of files and blocks and, in the future, to every larger number of smaller objects. Ozone fundamentally separates the namespace layer and the block layer allowing new namespace layers to be added in the future. Further, the use of RAFT protocol has allowed the storage layer to be self-consistent. We show how this technology helps a Hadoop user and also what it means for evolving HDFS in the future. We will also cover the technical details of Ozone.
Using Spark Streaming and NiFi for the next generation of ETL in the enterprise
In recent years, big data has moved from batch processing to stream-based processing since no one wants to wait hours or days to gain insights. Dozens of stream processing frameworks exist today and the same trend that occurred in the batch-based big data processing realm has taken place in the streaming world so that nearly every streaming framework now supports higher level relational operations.
On paper, combining Apache NiFi, Kafka, and Spark Streaming provides a compelling architecture option for building your next generation ETL data pipeline in near real time. What does this look like in an enterprise production environment to deploy and operationalized?
The newer Spark Structured Streaming provides fast, scalable, fault-tolerant, end-to-end exactly-once stream processing with elegant code samples, but is that the whole story?
We discuss the drivers and expected benefits of changing the existing event processing systems. In presenting the integrated solution, we will explore the key components of using NiFi, Kafka, and Spark, then share the good, the bad, and the ugly when trying to adopt these technologies into the enterprise. This session is targeted toward architects and other senior IT staff looking to continue their adoption of open source technology and modernize ingest/ETL processing. Attendees will take away lessons learned and experience in deploying these technologies to make their journey easier.
Containers and Big Data
As containerization continues to gain momentum and become a de facto standard for application deployment, challenges around containerization of big data workloads are coming to light. Great strides have been made within the open source communities towards running big data workloads in containers, but much is left to be done.
Apache Hadoop YARN is the modern distributed operating system for big data applications. It has morphed the Hadoop compute layer into a common resource-management platform that can host a wide variety of applications. At its core, YARN has a very powerful scheduler which enforces global cluster level invariants and helps sites manage user and operator expectations of elastic sharing, resource usage limits, SLAs, and more. YARN recently increased its support for Docker containerization and added a YARN service framework supporting long-running services.
In this session we will explore the emerging patterns and challenges related to containers and big data workloads, including running applications such as Apache Spark, Apache HBase, and Kubernetes in containers on YARN.

Meet HBase 2.0 and Phoenix-5.0
This talk will give an overview of two exciting releases for Apache HBase 2.0 and Phoenix 5.0. HBase provides a NoSQL column store on Hadoop for random, real-time read/write workloads. Phoenix provides SQL on top of HBase. HBase 2.0 contains a large number of features that were a long time in development, including rewritten region assignment, performance improvements (RPC, rewritten write pipeline, etc), async clients and WAL, a C++ client, offheaping memstore and other buffers, shading of dependencies, as well as a lot of other fixes and stability improvements. We will go into details on some of the most important improvements in the release, as well as what are the implications for the users in terms of API and upgrade paths. Phoenix 5.0 is the next big Phoenix release because of its integration with HBase 2.0 and a lot of performance improvements in support of secondary Indexes. It has many important new features such as encoded columns, Kafka and Hive integration, and many other performance improvements. This session will also describe the uses cases that HBase and Phoenix are a good architectural fit for.

Dataflow Management From Edge to Core with Apache NiFi
What is “dataflow?” — the process and tooling around gathering necessary information and getting it into a useful form to make insights available. Dataflow needs change rapidly — what was noise yesterday may be crucial data today, an API endpoint changes, or a service switches from producing CSV to JSON or Avro. In addition, developers may need to design a flow in a sandbox and deploy to QA or production — and those database passwords aren’t the same (hopefully). Learn about Apache NiFi — a robust and secure framework for dataflow development and monitoring.
Abstract: Identifying, collecting, securing, filtering, prioritizing, transforming, and transporting abstract data is a challenge faced by every organization. Apache NiFi and MiNiFi allow developers to create and refine dataflows with ease and ensure that their critical content is routed, transformed, validated, and delivered across global networks. Learn how the framework enables rapid development of flows, live monitoring and auditing, data protection and sharing. From IoT and machine interaction to log collection, NiFi can scale to meet the needs of your organization. Able to handle both small event messages and “big data” on the scale of terabytes per day, NiFi will provide a platform which lets both engineers and non-technical domain experts collaborate to solve the ingest and storage problems that have plagued enterprises.
Expected prior knowledge / intended audience: developers and data flow managers should be interested in learning about and improving their dataflow problems. The intended audience does not need experience in designing and modifying data flows.
Takeaways: Attendees will gain an understanding of dataflow concepts, data management processes, and flow management (including versioning, rollbacks, promotion between deployment environments, and various backing implementations).
Current uses: I am a committer and PMC member for the Apache NiFi, MiNiFi, and NiFi Registry projects and help numerous users deploy these tools to collect data from an incredibly diverse array of endpoints, aggregate, prioritize, filter, transform, and secure this data, and generate actionable insight from it. Current users of these platforms include many Fortune 100 companies, governments, startups, and individual users across fields like telecommunications, finance, healthcare, automotive, aerospace, and oil & gas, with use cases like fraud detection, logistics management, supply chain management, machine learning, IoT gateway, connected vehicles, smart grids, etc.
Solving Cybersecurity at Scale
With the rise of IoT and the increasing complexity of applications, clouds, networks and infrastructure, the battle to keep your data and your infrastructure safe from attackers is getting harder. As groups of bad actors collaborate, sharing information and offering illegal access, and botnets as a service, terabits of attack can be launched cheaply. Meanwhile, it’s hard to find enough security analysts to catch and prevent these attacks.
This is where community collaboration and open source efforts like Apache Metron come in. Metron presents a comprehensive framework for application and network, security built on Apache Hadoop and open source Streaming Analytics(ie Apache Nifi, Apache Kafka) tool’s highly scalable data management and processing stacks. Advanced features like profiling, machine learning, and visualization work with real-time streaming detection to make your SOC analysts more efficient, while the intrinsic extensibility of open source helps your data scientists get security insights out of the lab and into production fast.
We will discuss and demonstrate how some real-world businesses and managed service providers are using Apache Metron to identify and solve security threats at scale, and some approaches and ideas for how the platform can fit into your security architecture.

Apache Spark 2.3 has made similar strides too, introducing new features and resolving over 1300 JIRA issues. Likewise, Apache Spark 2.4 will have many JIRA issues resolved over 1100. In this talk, I want to skim and go through those notable features and changes.
Navigating Idiosyncrasies of IoT Development
While developing on Apache NiFi MiNiFI C++, my focus has been writing architectural details from Apache NiFi in C++. During this time I've learned of the myriad of applications in which IoT exists. In this presentation we'll discuss key lessons I've learned along with ways that we can help you navigate the IoT realm from the perspective of technical challenges that you will face.
We will begin with an overview of Apache NiFi MiNiFi C++ followed by discussions of system awareness. In doing so we'll focus on system monitoring for battery and network status. We'll look at how MiNIFi can be configured to monitor battery and network status to throttle itself and be a good steward of device management. In the same vein we'll discuss the idiosyncrasies that you must be aware of when dealing with common IoT use cases, such as connected cars and embedded devices on the move. Finally, we'll look at lessons we've learned in helping other developers write software in the IoT realm. MARC PARISI, Principal SW Engineer, Hortonworks
The First Mile - Edge and IoT Data Collection With Apache Nifi and MiniFi
Apache NiFi MiNiFi enables data collection in a brand new environment - small sensor footprint, intermittent or limited bandwidth distributed system, and disposable or short-lived hardware. You can prioritize this data or perform initial analysis on the edge, as well as immediately encrypt and protect it.
Concept: Apache NiFi offers a revolutionary data flow management system and extensive integration of existing data production, consumption and analysis ecosystems, all of which are robust data delivery and a (data) logging infrastructure It is protected by. Learn about the additional project Apache MiNiFi, which extends the scope of NiFi's power to the maximum. MiNiFi is a lightweight application that can be placed on hardware that is one order of magnitude smaller than the existing standard data collection platform and is less powerful. As a JVM-enabled native agent MiNiFi enables data gathering in a brand new environment - small sensor footprint, intermittent or limited bandwidth distributed system, and disposable or short-lived hardware. You can prioritize this data or perform initial analysis on the edge, as well as immediately encrypt and protect it. Regional governance and regulatory policies are applied to geopolitical boundaries and comply with legal requirements. And all of this configuration can be done from the existing NiFi and central control using the stable data UI that the data flow administrator has already liked and trusted.
Required prior knowledge / targeted participants: Developers and data flow administrators need some knowledge of Apache NiFi as a platform for routing, conversion, and data delivery through the system (a brief overview is provided ). In this talk we will focus on extending data collection, routing, data history, and NiFi control functions, through IoT / edge integration via MiNiFi.
Key Points: Participants will learn about the opportunity to collect and capture data flows close to the source of data, "edge", such as IoT devices, vehicles, machines, etc. Participants prioritize, filter, protect, and manipulate this data in the initial data lifecycle and understand the potential for data visibility and performance improvement.
Data in the Cloud Crash Course
Introduction
This workshop is a hands-on session to quickly deploy Hadoop and Streaming on AWS / Azure / Google Cloud.
Cloudbreak simplifies the deployment of Hadoop in cloud environments. It enables the enterprise to quickly run big data workloads in the cloud while optimizing the use of cloud resources.
Format
A short introductory lecture about Cloudbreak. This is followed by a walk through and lab leveraging Hadoop and Streaming in the Cloud with Cloudbreak.
Objective
To provide a quick and short hands-on introduction to Hadoop on the cloud. Review key benefits of cluster deployment automation.
This lab will use Cloudbreak to quickly and effortlessly stand up Hadoop and Streaming clusters in a cloud provider of your choice. The lab shows the use of Ambari blueprints that are your declarative definitions of your Hadoop or Streaming clusters. Steps to dynamically change these blueprints and use external databases and external authentication sources and in essence showing a way to provide Shared Authentication, Authorization and Audit across ephemeral and long-lasting clusters. However it is not limited to only custom blueprints, the lab also shows how Cloudbreak provides easy to use custom scripts called recipes that can be executed before or after Ambari start or after cluster installation.
Fast SQL on Hadoop, really?
How is it that one system can query terabytes of data, yet still provide interactive query support? This talk will discuss two of the underlying technologies that allow Apache Hive to support fast query response, both on-premise in HDFS and in cloud object stores such as S3 and WASB.
LLAP was introduced in Hive 2.6. It provides standing processes that securely cache Hive’s columnar data and can do query processing without ever needing to start tasks in Hadoop. We will cover LLAP’s architecture, intended uses cases, and performance numbers for both on-premise and in the cloud.
The second technology is the integration of Hive with Apache Druid. Druid excels at low-latency, interactive queries over streaming data. Its method of storing data makes it very well suited for OLAP style queries. We will cover how Hive can be integrated with Druid to support real-time streaming of data from Kafka and OLAP queries.
Meet HBase 2.0 and Phoenix 5.0
This talk will give an overview of two exciting releases for Apache HBase 2.0 and Phoenix 5.0. HBase provides a NoSQL column store on Hadoop for random, real-time read/write workloads. Phoenix provides SQL on top of HBase. HBase 2.0 contains a large number of features that were a long time in development, including rewritten region assignment, performance improvements (RPC, rewritten write pipeline, etc), async clients and WAL, a C++ client, offheaping memstore and other buffers, shading of dependencies, as well as a lot of other fixes and stability improvements. We will go into details on some of the most important improvements in the release, as well as what are the implications for the users in terms of API and upgrade paths. Phoenix 5.0 is the next big Phoenix release because of its integration with HBase 2.0 and a lot of performance improvements in support of secondary Indexes. It has many important new features such as encoded columns, Kafka and Hive integration, and many other performance improvements. This session will also describe the uses cases that HBase and Phoenix are a good architectural fit for.

Curing the Kafka Blindness – Streams Messaging Manager
Companies who use Kafka today struggle with monitoring and managing Kafka clusters. Kafka is a key backbone of IoT streaming analytics applications. The challenge is understanding what is going on overall in the Kafka cluster including performance, issues and message flows. No open source tool caters to the needs of different users that work with Kafka: DevOps/developers, platform team, and security/governance teams. See how the new Hortonworks Streams Messaging Manager enables users to visualize their entire Kafka environment end-to-end and simplifies Kafka operations.
In this session learn how SMM visualizes the intricate details of how Apache Kafka functions in real time while simultaneously surfacing every nuance of tuning, optimizing, and measuring input and output. SMM will assist users to quickly understand and operate Kafka while providing the much-needed transparency that sophisticated and experienced users need to avoid all the pitfalls of running a Kafka cluster.

Containers and Big Data
As containerization continues to gain momentum and become a de facto standard for application deployment, challenges around containerization of big data workloads are coming to light. Great strides have been made within the open source communities towards running big data workloads in containers, but much is left to be done.
Apache Hadoop YARN is the modern distributed operating system for big data applications. It has morphed the Hadoop compute layer into a common resource-management platform that can host a wide variety of applications. At its core, YARN has a very powerful scheduler which enforces global cluster level invariants and helps sites manage user and operator expectations of elastic sharing, resource usage limits, SLAs, and more. YARN recently increased its support for Docker containerization and added a YARN service framework supporting long-running services.
In this session we will explore the emerging patterns and challenges related to containers and big data workloads, including running applications such as Apache Spark, Apache HBase, and Kubernetes in containers on YARN.

How to Ingest 16 Billion Records Per Day into your Hadoop Environment
In a modern society, mobile networks has become one of the most important infrastructure components. The availability of a mobile network has become even essential in areas like health care and machine to machine communication.
In 2016, Telefónica Germany begun the Customer Experience Management (CEM) project to get KPI out of the mobile network describing the participant’s experience while using the Telefónica’s mobile network. These KPI help to plan and create a better mobile network where improvements are indicated.
Telefónica is using Hortonworks HDF solution to ingest 16 billion records a day which are generated by CEM. To achieve the best out of HDF abilities some customizations have been made:
1.) Custom processors have been written to comply with data privacy rules.
2.) Nifi is running in Docker containers within a Kubernetes cluster to increase reliability of the ingestion system.
Finally, the data is presented in Hive tables and Kafka topics to be further processed. In this talk, we will present the CEM use case and how it is technically implemented as stated in (1) and (2). Most interesting part for the audience should be our experiences we have made using HDF in a Docker/Kubernetes environment since this solution is not yet officially supported.
Apache Nifi Crash Course
This workshop will provide a hands on introduction to simple event data processing and data flow processing using a Sandbox on students’ personal machines.
Format: A short introductory lecture to Apache NiFi and computing used in the lab followed by a demo, lab exercises and a Q&A session. The lecture will be followed by lab time to work through the lab exercises and ask questions.
Objective: To provide a quick and short hands-on introduction to Apache NiFi. In the lab, you will install and use Apache NiFi to collect, conduct and curate data-in-motion and data-at-rest with NiFi. You will learn how to connect and consume streaming sensor data, filter and transform the data and persist to multiple data sources.
Pre-requisites: Registrants must bring a laptop that has the latest VirtualBox installed and an image for Hortonworks DataFlow (HDF) Sandbox will be provided.

Hadoop: The Unintended Benefits
The document discusses some unintended benefits that the Department of Home Affairs discovered from implementing Hadoop. It describes how Hadoop was initially used for passenger systems and the Teradata data warehouse, but then enabled additional uses. Solr was used to enable fast search of billions of rows across Hadoop, improving on slow full table scans in Teradata. A graph database called JanusGraph was also implemented on Hadoop to enable relationship analysis and predictive analytics for security use cases. The document outlines the architectures used and lessons learned around performance, security, and managing expectations for these new capabilities enabled by Hadoop.
Connecting the Drops with Apache NiFi & Apache MiNiFi
Demand for increased capture of information to drive analytic insights into an organizations' assets and infrastructure is growing at unprecedented rates. However, as data volume growth soars, the ability to provide seamless ingestion pipelines becomes operationally complex as the magnitude of data sources and types expands.
This talk will focus on the efforts of the Apache NiFi community including subproject, MiNiFi; an agent based architecture and its relation to the core Apache NiFi project. MiNiFi is focused on providing a platform that meets and adapts to where data is born while providing the core tenets of NiFi in provenance, security, and command and control. These capabilities provide versatile avenues for the bi-directional exchange of information across data and control planes while dealing with the constraints of operation at opposite ends of the scale spectrum tackling the first and last miles of dataflow management.
We will highlight ongoing and new efforts in the community to provide greater flexibility with deployment and configuration management of flows. Versioned flows provide greater operational flexibility and serve as a powerful foundation to orchestrate the collection and transmission from the point of data's inception through to its transmission to consumers and processing systems.
Apache Hadoop YARN: state of the union
The document provides an overview of the state of Apache Hadoop YARN. Key themes discussed include scaling to support very large clusters of 100,000+ nodes, improved global and fast scheduling capabilities, richer placement constraints, and enhanced support for containers, resources like GPUs and FPGAs, and services. The YARN community continues to grow with over 450 contributors.
Apache Hadoop 3 updates with migration story
The document discusses migrating Hadoop clusters from version 2 to version 3. It provides an overview of new features in HDFS, YARN, and other components in Hadoop 3, including erasure coding in HDFS, global scheduling and new resource types in YARN. It also covers important considerations for upgrading such as recommended source and target versions, upgrade mechanisms, tooling changes, and ensuring Java 8 is used.

Apache Hadoop YARN: state of the union
Apache Hadoop YARN is the modern distributed operating system for big data applications. It morphed the Hadoop compute layer to be a common resource management platform that can host a wide variety of applications. Many organizations leverage YARN in building their applications on top of Hadoop without themselves repeatedly worrying about resource management, isolation, multi-tenancy issues, etc.
In this talk, we’ll start with the current status of Apache Hadoop YARN—how it is used today in deployments large and small. We'll then move on to the exciting present and future of YARN—features that are further strengthening YARN as the first class resource management platform for data centers running enterprise Hadoop.
We’ll discuss the current status as well as the future promise of features and initiatives like: powerful container placement, global scheduling, support for machine learning and deep learning workloads through GPU and FPGA support, extreme scale with YARN federation, containerized apps on YARN, support for long-running services (alongside applications) natively without any changes, seamless application upgrades, powerful scheduling features like application priorities, intra-queue preemption across applications, and operational enhancements including insights through Timeline Service V2, a new web UI, and better queue management.

Dataflow Management From Edge to Core with Apache NiFi
What is “dataflow?” — the process and tooling around gathering necessary information and getting it into a useful form to make insights available. Dataflow needs change rapidly — what was noise yesterday may be crucial data today, an API endpoint changes, or a service switches from producing CSV to JSON or Avro. In addition, developers may need to design a flow in a sandbox and deploy to QA or production — and those database passwords aren’t the same (hopefully). Learn about Apache NiFi — a robust and secure framework for dataflow development and monitoring.
Abstract: Identifying, collecting, securing, filtering, prioritizing, transforming, and transporting abstract data is a challenge faced by every organization. Apache NiFi and MiNiFi allow developers to create and refine dataflows with ease and ensure that their critical content is routed, transformed, validated, and delivered across global networks. Learn how the framework enables rapid development of flows, live monitoring and auditing, data protection and sharing. From IoT and machine interaction to log collection, NiFi can scale to meet the needs of your organization. Able to handle both small event messages and “big data” on the scale of terabytes per day, NiFi will provide a platform which lets both engineers and non-technical domain experts collaborate to solve the ingest and storage problems that have plagued enterprises.
Expected prior knowledge / intended audience: developers and data flow managers should be interested in learning about and improving their dataflow problems. The intended audience does not need experience in designing and modifying data flows.
Takeaways: Attendees will gain an understanding of dataflow concepts, data management processes, and flow management (including versioning, rollbacks, promotion between deployment environments, and various backing implementations).
Current uses: I am a committer and PMC member for the Apache NiFi, MiNiFi, and NiFi Registry projects and help numerous users deploy these tools to collect data from an incredibly diverse array of endpoints, aggregate, prioritize, filter, transform, and secure this data, and generate actionable insight from it. Current users of these platforms include many Fortune 100 companies, governments, startups, and individual users across fields like telecommunications, finance, healthcare, automotive, aerospace, and oil & gas, with use cases like fraud detection, logistics management, supply chain management, machine learning, IoT gateway, connected vehicles, smart grids, etc.
Solving Cybersecurity at Scale
With the rise of IoT and the increasing complexity of applications, clouds, networks and infrastructure, the battle to keep your data and your infrastructure safe from attackers is getting harder. As groups of bad actors collaborate, sharing information and offering illegal access, and botnets as a service, terabits of attack can be launched cheaply. Meanwhile, it’s hard to find enough security analysts to catch and prevent these attacks.
This is where community collaboration and open source efforts like Apache Metron come in. Metron presents a comprehensive framework for application and network, security built on Apache Hadoop and open source Streaming Analytics(ie Apache Nifi, Apache Kafka) tool’s highly scalable data management and processing stacks. Advanced features like profiling, machine learning, and visualization work with real-time streaming detection to make your SOC analysts more efficient, while the intrinsic extensibility of open source helps your data scientists get security insights out of the lab and into production fast.
We will discuss and demonstrate how some real-world businesses and managed service providers are using Apache Metron to identify and solve security threats at scale, and some approaches and ideas for how the platform can fit into your security architecture.

Using Spark Streaming and NiFi for the Next Generation of ETL in the Enterprise
In recent years, big data has moved from batch processing to stream-based processing since no one wants to wait hours or days to gain insights. Dozens of stream processing frameworks exist today and the same trend that occurred in the batch-based big data processing realm has taken place in the streaming world so that nearly every streaming framework now supports higher level relational operations.
On paper, combining Apache NiFi, Kafka, and Spark Streaming provides a compelling architecture option for building your next generation ETL data pipeline in near real time. What does this look like in an enterprise production environment to deploy and operationalized?
The newer Spark Structured Streaming provides fast, scalable, fault-tolerant, end-to-end exactly-once stream processing with elegant code samples, but is that the whole story?
We discuss the drivers and expected benefits of changing the existing event processing systems. In presenting the integrated solution, we will explore the key components of using NiFi, Kafka, and Spark, then share the good, the bad, and the ugly when trying to adopt these technologies into the enterprise. This session is targeted toward architects and other senior IT staff looking to continue their adoption of open source technology and modernize ingest/ETL processing. Attendees will take away lessons learned and experience in deploying these technologies to make their journey easier.

In the same vein we'll discuss the idiosyncrasies that you must be aware of when dealing with common IoT use cases, such as connected cars and embedded devices on the move. Finally, we'll look at lessons we've learned in helping other developers write software in the IoT realm. MARC PARISI, Principal SW Engineer, Hortonworks
The First Mile - Edge and IoT Data Collection With Apache Nifi and MiniFi
Apache NiFi MiNiFi enables data collection in a brand new environment - small sensor footprint, intermittent or limited bandwidth distributed system, and disposable or short-lived hardware. You can prioritize this data or perform initial analysis on the edge, as well as immediately encrypt and protect it.
Concept: Apache NiFi offers a revolutionary data flow management system and extensive integration of existing data production, consumption and analysis ecosystems, all of which are robust data delivery and a (data) logging infrastructure It is protected by. Learn about the additional project Apache MiNiFi, which extends the scope of NiFi's power to the maximum. MiNiFi is a lightweight application that can be placed on hardware that is one order of magnitude smaller than the existing standard data collection platform and is less powerful. As a JVM-enabled native agent MiNiFi enables data gathering in a brand new environment - small sensor footprint, intermittent or limited bandwidth distributed system, and disposable or short-lived hardware. You can prioritize this data or perform initial analysis on the edge, as well as immediately encrypt and protect it. Regional governance and regulatory policies are applied to geopolitical boundaries and comply with legal requirements. And all of this configuration can be done from the existing NiFi and central control using the stable data UI that the data flow administrator has already liked and trusted.
Required prior knowledge / targeted participants: Developers and data flow administrators need some knowledge of Apache NiFi as a platform for routing, conversion, and data delivery through the system (a brief overview is provided ). In this talk we will focus on extending data collection, routing, data history, and NiFi control functions, through IoT / edge integration via MiNiFi.
Key Points: Participants will learn about the opportunity to collect and capture data flows close to the source of data, "edge", such as IoT devices, vehicles, machines, etc. Participants prioritize, filter, protect, and manipulate this data in the initial data lifecycle and understand the potential for data visibility and performance improvement.
Data in the Cloud Crash Course
Introduction
This workshop is a hands-on session to quickly deploy Hadoop and Streaming on AWS / Azure / Google Cloud.
Cloudbreak simplifies the deployment of Hadoop in cloud environments. It enables the enterprise to quickly run big data workloads in the cloud while optimizing the use of cloud resources.
Format
A short introductory lecture about Cloudbreak. This is followed by a walk through and lab leveraging Hadoop and Streaming in the Cloud with Cloudbreak.
Objective
To provide a quick and short hands-on introduction to Hadoop on the cloud. Review key benefits of cluster deployment automation.
This lab will use Cloudbreak to quickly and effortlessly stand up Hadoop and Streaming clusters in a cloud provider of your choice. The lab shows the use of Ambari blueprints that are your declarative definitions of your Hadoop or Streaming clusters. Steps to dynamically change these blueprints and use external databases and external authentication sources and in essence showing a way to provide Shared Authentication, Authorization and Audit across ephemeral and long-lasting clusters. However it is not limited to only custom blueprints, the lab also shows how Cloudbreak provides easy to use custom scripts called recipes that can be executed before or after Ambari start or after cluster installation.
Fast SQL on Hadoop, really?
How is it that one system can query terabytes of data, yet still provide interactive query support? This talk will discuss two of the underlying technologies that allow Apache Hive to support fast query response, both on-premise in HDFS and in cloud object stores such as S3 and WASB.
LLAP was introduced in Hive 2.6. It provides standing processes that securely cache Hive’s columnar data and can do query processing without ever needing to start tasks in Hadoop. We will cover LLAP’s architecture, intended uses cases, and performance numbers for both on-premise and in the cloud.
The second technology is the integration of Hive with Apache Druid. Druid excels at low-latency, interactive queries over streaming data. Its method of storing data makes it very well suited for OLAP style queries. We will cover how Hive can be integrated with Druid to support real-time streaming of data from Kafka and OLAP queries.

Containers and Big Data
As containerization continues to gain momentum and become a de facto standard for application deployment, challenges around containerization of big data workloads are coming to light. Great strides have been made within the open source communities towards running big data workloads in containers, but much is left to be done.
Apache Hadoop YARN is the modern distributed operating system for big data applications. It has morphed the Hadoop compute layer into a common resource-management platform that can host a wide variety of applications. At its core, YARN has a very powerful scheduler which enforces global cluster level invariants and helps sites manage user and operator expectations of elastic sharing, resource usage limits, SLAs, and more. YARN recently increased its support for Docker containerization and added a YARN service framework supporting long-running services.
In this session we will explore the emerging patterns and challenges related to containers and big data workloads, including running applications such as Apache Spark, Apache HBase, and Kubernetes in containers on YARN.

Apache Hadoop YARN: Present and Future
Apache Hadoop YARN is the modern Distributed Operating System. It enables the Hadoop compute layer to be a common resource-management platform that can host a wide variety of applications. Multiple organizations are able to leverage YARN in building their applications on top of Hadoop without themselves repeatedly worrying about resource management, isolation, multi-tenancy issues etc.
In this talk, we’ll first hit the ground with the current status of Apache Hadoop YARN – how it is faring today in deployments large and small. We will cover different types of YARN deployments, in different environments and scale.
We'll then move on to the exciting present & future of YARN – features that are further strengthening YARN as the first-class resource-management platform for datacenters running enterprise Hadoop. We’ll discuss the current status as well as the future promise of features and initiatives like – 10x scheduler throughput improvements, docker containers support on YARN, support for long running services (alongside applications) natively without any changes, seamless application upgrades, fine-grained isolation for multi-tenancy using CGroups on disk & network resources, powerful scheduling features like application priorities, intra-queue preemption across applications and operational enhancements including insights through Timeline Service V2, a new web UI and better queue management.
Hadoop Summit San Jose 2015: YARN - Past, Present and Future
The document discusses the past, present, and future of Apache Hadoop YARN. It describes how YARN was created to address limitations in MapReduce and provide a more flexible resource management framework. The presentation outlines major releases of YARN from 2010 to 2015, focusing on new features like rolling upgrades, long-running services, node labels, and improved usability tools. It envisions future enhancements such as per-queue scheduling policies, reservations, containerized applications, and improved network and disk isolation.
Lessons learned running a container cloud on YARN
Apache Hadoop YARN is the resource and application manager for Apache Hadoop. In the past, YARN only supported launching containers as processes. However, as containerization has become extremely popular, more and more users wanted support for launching Docker containers. With recent changes, YARN now supports running Docker containers alongside process containers. Coupled with the newly added support for long-running services on YARN, this allows a host of new possibilities.
In this talk, we'll present how to run a container cloud on YARN. Leveraging the support in YARN for Docker and long-running services, we can allow users to easily spin up sets of Docker containers for their applications. These containers can be self contained or wired up to form more complex applications. We will go over some of the lessons we learned as part of our experiences handling issues such as resource management, debugging application failures, running Docker, service discovery, etc.

- Running over 5.8 million containers and 1.1 million tests on the container cloud with improved hardware utilization and test speed.
- Challenges involved issues like IP management, Docker storage drivers causing kernel panics, user namespacing limitations, and image management.
- Solutions involved allocating IP addresses, testing storage configurations, running containers as a common user, and managing a private image registry for cleanup.
Apache Hadoop YARN: Past, Present and Future
The document discusses the past, present, and future of Apache Hadoop YARN. It describes how YARN started as a sub-project of Hadoop to improve its resource management capabilities. Today, YARN is central to modern data architectures, providing centralized resource management and scheduling. Going forward, YARN aims to better support containers, simplified APIs, treating services as first-class citizens, and enhance its user experience.
What's new in apache hive
Apache Hive is a rapidly evolving project which continues to enjoy great adoption in big data ecosystem. Although, Hive started primarily as batch ingestion and reporting tool, community is hard at work in improving it along many different dimensions and use cases. This talk will provide an overview of latest and greatest features and optimizations which have landed in project over last year. Materialized view, micro managed tables and workload management are some noteworthy features.
I will deep dive into some optimizations which promise to provide major performance gains. Support for ACID tables has also improved considerably. Although some of these features and enhancements are not novel but have existed for years in other DB systems, implementing them on Hive poses some unique challenges and results in lessons which are generally applicable in many other contexts. I will also provide a glimpse of what is expected to come in near future.

Developing Applications with Hadoop 2.0 and YARN by Abhijit Lele
Hadoop 2.0 is approaching. A defining characteristic of Hadoop 2.0 is its next generation resource management framework called YARN. YARN enables Hadoop to grow beyond its MapReduce origins to embrace multiple workloads spanning interactive queries, batch processing, streaming & more.
Running Non-MapReduce Big Data Applications on Apache Hadoop
Apache Hadoop has become popular from its specialization in the execution of MapReduce programs. However, it has been hard to leverage existing Hadoop infrastructure for various other processing paradigms such as real-time streaming, graph processing and message-passing. That was true until the introduction of Apache Hadoop YARN in Apache Hadoop 2.0. YARN supports running arbitrary processing paradigms on the same Hadoop cluster. This allows for development of newer frameworks as well as more efficient implementations of existing frameworks that can all run on and share the resources of a single multi-tenant YARN cluster. This talk gives a brief introduction to YARN. We will illustrate how to create applications and how to best make use of YARN. We will show examples of different applications such as Apache Tez and Apache Samza that can leverage YARN and present best practices/guidelines on building applications on top of Apache Hadoop YARN.
Apache Hadoop YARN: Present and Future
Vinod Kumar Vavilapalli and Jian He presented on Apache Hadoop YARN, the next generation architecture for Hadoop. They discussed YARN's role as a data operating system and resource management platform. They outlined YARN's current capabilities and highlighted several features in development, including resource manager high availability, the YARN timeline server, and improved scheduling. They also discussed how YARN enables new applications beyond MapReduce and the growing ecosystem of projects supported by YARN.
Apache Hadoop YARN: best practices
This document provides best practices for YARN administrators and application developers. For administrators, it discusses YARN configuration, enabling ResourceManager high availability, configuring schedulers like Capacity Scheduler and Fair Scheduler, sizing containers, configuring NodeManagers, log aggregation, and metrics. For application developers, it discusses whether to use an existing framework or develop a native application, understanding YARN components, writing the client, and writing the ApplicationMaster.
High throughput data replication over RAFT
Raft protocol has been successfully used for consistent metadata replication; however, using it for data replication poses unique challenges. Apache Ratis is a RAFT implementation targeted at high throughput data replication problems. Apache Ratis is being successfully used as a consensus protocol for data stored in Ozone (object store) and Quadra(block device) to provide data throughput that saturates the network links and disk bandwidths.
Pluggable nature of Ratis renders it useful for multiple use cases including high availability, data or metadata replication, and ensuring consistency semantics.
This talk presents the design challenges to achieve high throughput and how Apache Ratis addresses them. We talk about specific optimizations that have been implemented to minimize overheads and scale up the throughput while maintaining correctness of the consistency protocol. The talk also explains how systems like Ozone take advantage of Ratis’s implementation choices to achieve scale. We will discuss the current performance numbers and also future optimizations. MUKUL KUMAR SINGH, Staff Software Engineer, Hortonworks and LOKESH JAIN, Software Engineer, Hortonworks
Apache Hadoop YARN: Past, Present and Future
This document provides an overview of the past, present, and future of Apache Hadoop YARN. It discusses how YARN has evolved from Apache Hadoop 2.6/2.7 to now support 2.8 with features like dynamic resource configuration, container resizing, and Docker support. Upcoming work includes support for arbitrary resource types, federation of multiple YARN clusters, and a new ResourceManager UI. The future of YARN scheduling may include distributed scheduling, intra-queue preemption, and scheduling based on actual resource usage.

Floating on a RAFT: HBase Durability with Apache Ratis
In a world with a myriad of distributed storage systems to choose from, the majority of Apache HBase clusters still rely on Apache HDFS. Theoretically, any distributed file system could be used by HBase. One major reason HDFS is predominantly used are the specific durability requirements of HBase's write-ahead log (WAL) and HDFS providing that guarantee correctly. However, HBase's use of HDFS for WALs can be replaced with sufficient effort.
This talk will cover the design of a "Log Service" which can be embedded inside of HBase that provides a sufficient level of durability that HBase requires for WALs. Apache Ratis (incubating) is a library-implementation of the RAFT consensus protocol in Java and is used to build this Log Service. We will cover the design choices of the Ratis Log Service, comparing and contrasting it to other log-based systems that exist today. Next, we'll cover how the Log Service "fits" into HBase and the necessary changes to HBase which enable this. Finally, we'll discuss how the Log Service can simplify the operational burden of HBase.
Tracking Crime as It Occurs with Apache Phoenix, Apache HBase and Apache NiFi
Utilizing Apache NiFi we read various open data REST APIs and camera feeds to ingest crime and related data real-time streaming it into HBase and Phoenix tables. HBase makes an excellent storage option for our real-time time series data sources. We can immediately query our data utilizing Apache Zeppelin against Phoenix tables as well as Hive external tables to HBase.
Apache Phoenix tables also make a great option since we can easily put microservices on top of them for application usage. I have an example Spring Boot application that reads from our Philadelphia crime table for front-end web applications as well as RESTful APIs.
Apache NiFi makes it easy to push records with schemas to HBase and insert into Phoenix SQL tables.

HBase Tales From the Trenches - Short stories about most common HBase operati...
Whilst HBase is the most logical answer for use cases requiring random, realtime read/write access to Big Data, it may not be so trivial to design applications that make most of its use, neither the most simple to operate. As it depends/integrates with other components from Hadoop ecosystem (Zookeeper, HDFS, Spark, Hive, etc) or external systems ( Kerberos, LDAP), and its distributed nature requires a "Swiss clockwork" infrastructure, many variables are to be considered when observing anomalies or even outages. Adding to the equation there's also the fact that HBase is still an evolving product, with different release versions being used currently, some of those can carry genuine software bugs. On this presentation, we'll go through the most common HBase issues faced by different organisations, describing identified cause and resolution action over my last 5 years supporting HBase to our heterogeneous customer base.

LocationTech GeoMesa enables spatial and spatiotemporal indexing and queries for HBase and Accumulo. In this talk, after an overview of GeoMesa’s capabilities in the Cloudera ecosystem, we will dive into how GeoMesa leverages Accumulo’s Iterator interface and HBase’s Filter and Coprocessor interfaces. The goal will be to discuss both what spatial operations can be pushed down into the distributed database and also how the GeoMesa codebase is organized to allow for consistent use across the two database systems.
Managing the Dewey Decimal System
OCLC has been using HBase since 2012 to enable single-search-box access to over a billion items from your library and the world’s library collection. This talk will provide an overview of how HBase is structured to provide this information and some of the challenges they have encountered to scale to support the world catalog and how they have overcome them.
Practical NoSQL: Accumulo's dirlist Example
Many individuals/organizations have a desire to utilize NoSQL technology, but often lack an understanding of how the underlying functional bits can be utilized to enable their use case. This situation can result in drastic increases in the desire to put the SQL back in NoSQL.
Since the initial commit, Apache Accumulo has provided a number of examples to help jumpstart comprehension of how some of these bits function as well as potentially help tease out an understanding of how they might be applied to a NoSQL friendly use case. One very relatable example demonstrates how Accumulo could be used to emulate a filesystem (dirlist).
In this session we will walk through the dirlist implementation. Attendees should come away with an understanding of the supporting table designs, a simple text search supporting a single wildcard (on file/directory names), and how the dirlist elements work together to accomplish its feature set. Attendees should (hopefully) also come away with a justification for sometimes keeping the SQL out of NoSQL.
HBase Global Indexing to support large-scale data ingestion at Uber
Danny Chen presented on Uber's use of HBase for global indexing to support large-scale data ingestion. Uber uses HBase to provide a global view of datasets ingested from Kafka and other data sources. To generate indexes, Spark jobs are used to transform data into HFiles, which are loaded into HBase tables. Given the large volumes of data, techniques like throttling HBase access and explicit serialization are used. The global indexing solution supports requirements for high throughput, strong consistency and horizontal scalability across Uber's data lake.
Scaling Cloud-Scale Translytics Workloads with Omid and Phoenix
Recently, Apache Phoenix has been integrated with Apache (incubator) Omid transaction processing service, to provide ultra-high system throughput with ultra-low latency overhead. Phoenix has been shown to scale beyond 0.5M transactions per second with sub-5ms latency for short transactions on industry-standard hardware. On the other hand, Omid has been extended to support secondary indexes, multi-snapshot SQL queries, and massive-write transactions.
These innovative features make Phoenix an excellent choice for translytics applications, which allow converged transaction processing and analytics. We share the story of building the next-gen data tier for advertising platforms at Verizon Media that exploits Phoenix and Omid to support multi-feed real-time ingestion and AI pipelines in one place, and discuss the lessons learned.
Building the High Speed Cybersecurity Data Pipeline Using Apache NiFi
This document discusses using Apache NiFi to build a high-speed cyber security data pipeline. It outlines the challenges of ingesting, transforming, and routing large volumes of security data from various sources to stakeholders like security operations centers, data scientists, and executives. It proposes using NiFi as a centralized data gateway to ingest data from multiple sources using a single entry point, transform the data according to destination needs, and reliably deliver the data while avoiding issues like network traffic and data duplication. The document provides an example NiFi flow and discusses metrics from processing over 20 billion events through 100+ production flows and 1000+ transformations.
Supporting Apache HBase : Troubleshooting and Supportability Improvements
This document discusses supporting Apache HBase and improving troubleshooting and supportability. It introduces two Cloudera employees who work on HBase support and provides an overview of typical troubleshooting scenarios for HBase like performance degradation, process crashes, and inconsistencies. The agenda covers using existing tools like logs and metrics to troubleshoot HBase performance issues with a general approach, and introduces htop as a real-time monitoring tool for HBase.
Security Framework for Multitenant Architecture
In the healthcare sector, data security, governance, and quality are crucial for maintaining patient privacy and ensuring the highest standards of care. At Florida Blue, the leading health insurer of Florida serving over five million members, there is a multifaceted network of care providers, business users, sales agents, and other divisions relying on the same datasets to derive critical information for multiple applications across the enterprise. However, maintaining consistent data governance and security for protected health information and other extended data attributes has always been a complex challenge that did not easily accommodate the wide range of needs for Florida Blue’s many business units. Using Apache Ranger, we developed a federated Identity & Access Management (IAM) approach that allows each tenant to have their own IAM mechanism. All user groups and roles are propagated across the federation in order to determine users’ data entitlement and access authorization; this applies to all stages of the system, from the broadest tenant levels down to specific data rows and columns. We also enabled audit attributes to ensure data quality by documenting data sources, reasons for data collection, date and time of data collection, and more. In this discussion, we will outline our implementation approach, review the results, and highlight our “lessons learned.”
Presto: Optimizing Performance of SQL-on-Anything Engine
Presto, an open source distributed SQL engine, is widely recognized for its low-latency queries, high concurrency, and native ability to query multiple data sources. Proven at scale in a variety of use cases at Airbnb, Bloomberg, Comcast, Facebook, FINRA, LinkedIn, Lyft, Netflix, Twitter, and Uber, in the last few years Presto experienced an unprecedented growth in popularity in both on-premises and cloud deployments over Object Stores, HDFS, NoSQL and RDBMS data stores.
With the ever-growing list of connectors to new data sources such as Azure Blob Storage, Elasticsearch, Netflix Iceberg, Apache Kudu, and Apache Pulsar, recently introduced Cost-Based Optimizer in Presto must account for heterogeneous inputs with differing and often incomplete data statistics. This talk will explore this topic in detail as well as discuss best use cases for Presto across several industries. In addition, we will present recent Presto advancements such as Geospatial analytics at scale and the project roadmap going forward.
Introducing MlFlow: An Open Source Platform for the Machine Learning Lifecycl...
Specialized tools for machine learning development and model governance are becoming essential. MlFlow is an open source platform for managing the machine learning lifecycle. Just by adding a few lines of code in the function or script that trains their model, data scientists can log parameters, metrics, artifacts (plots, miscellaneous files, etc.) and a deployable packaging of the ML model. Every time that function or script is run, the results will be logged automatically as a byproduct of those lines of code being added, even if the party doing the training run makes no special effort to record the results. MLflow application programming interfaces (APIs) are available for the Python, R and Java programming languages, and MLflow sports a language-agnostic REST API as well. Over a relatively short time period, MLflow has garnered more than 3,300 stars on GitHub , almost 500,000 monthly downloads and 80 contributors from more than 40 companies. Most significantly, more than 200 companies are now using MLflow. We will demo MlFlow Tracking , Project and Model components with Azure Machine Learning (AML) Services and show you how easy it is to get started with MlFlow on-prem or in the cloud.
Extending Twitter's Data Platform to Google Cloud
Twitter's Data Platform is built using multiple complex open source and in house projects to support Data Analytics on hundreds of petabytes of data. Our platform support storage, compute, data ingestion, discovery and management and various tools and libraries to help users for both batch and realtime analytics. Our DataPlatform operates on multiple clusters across different data centers to help thousands of users discover valuable insights. As we were scaling our Data Platform to multiple clusters, we also evaluated various cloud vendors to support use cases outside of our data centers. In this talk we share our architecture and how we extend our data platform to use cloud as another datacenter. We walk through our evaluation process, challenges we faced supporting data analytics at Twitter scale on cloud and present our current solution. Extending Twitter's Data platform to cloud was complex task which we deep dive in this presentation.
Event-Driven Messaging and Actions using Apache Flink and Apache NiFi
At Comcast, our team has been architecting a customer experience platform which is able to react to near-real-time events and interactions and deliver appropriate and timely communications to customers. By combining the low latency capabilities of Apache Flink and the dataflow capabilities of Apache NiFi we are able to process events at high volume to trigger, enrich, filter, and act/communicate to enhance customer experiences. Apache Flink and Apache NiFi complement each other with their strengths in event streaming and correlation, state management, command-and-control, parallelism, development methodology, and interoperability with surrounding technologies. We will trace our journey from starting with Apache NiFi over three years ago and our more recent introduction of Apache Flink into our platform stack to handle more complex scenarios. In this presentation we will compare and contrast which business and technical use cases are best suited to which platform and explore different ways to integrate the two platforms into a single solution.
Securing Data in Hybrid on-premise and Cloud Environments using Apache Ranger
Companies are increasingly moving to the cloud to store and process data. One of the challenges companies have is in securing data across hybrid environments with easy way to centrally manage policies. In this session, we will talk through how companies can use Apache Ranger to protect access to data both in on-premise as well as in cloud environments. We will go into details into the challenges of hybrid environment and how Ranger can solve it. We will also talk through how companies can further enhance the security by leveraging Ranger to anonymize or tokenize data while moving into the cloud and de-anonymize dynamically using Apache Hive, Apache Spark or when accessing data from cloud storage systems. We will also deep dive into the Ranger’s integration with AWS S3, AWS Redshift and other cloud native systems. We will wrap it up with an end to end demo showing how policies can be created in Ranger and used to manage access to data in different systems, anonymize or de-anonymize data and track where data is flowing.
Big Data Meets NVM: Accelerating Big Data Processing with Non-Volatile Memory...
Advanced Big Data Processing frameworks have been proposed to harness the fast data transmission capability of Remote Direct Memory Access (RDMA) over high-speed networks such as InfiniBand, RoCEv1, RoCEv2, iWARP, and OmniPath. However, with the introduction of the Non-Volatile Memory (NVM) and NVM express (NVMe) based SSD, these designs along with the default Big Data processing models need to be re-assessed to discover the possibilities of further enhanced performance. In this talk, we will present, NRCIO, a high-performance communication runtime for non-volatile memory over modern network interconnects that can be leveraged by existing Big Data processing middleware. We will show the performance of non-volatile memory-aware RDMA communication protocols using our proposed runtime and demonstrate its benefits by incorporating it into a high-performance in-memory key-value store, Apache Hadoop, Tez, Spark, and TensorFlow. Evaluation results illustrate that NRCIO can achieve up to 3.65x performance improvement for representative Big Data processing workloads on modern data centers.
Computer Vision: Coming to a Store Near You
Background: Some early applications of Computer Vision in Retail arose from e-commerce use cases - but increasingly, it is being used in physical stores in a variety of new and exciting ways, such as:
● Optimizing merchandising execution, in-stocks and sell-thru
● Enhancing operational efficiencies, enable real-time customer engagement
● Enhancing loss prevention capabilities, response time
● Creating frictionless experiences for shoppers
Abstract: This talk will cover the use of Computer Vision in Retail, the implications to the broader Consumer Goods industry and share business drivers, use cases and benefits that are unfolding as an integral component in the remaking of an age-old industry.
We will also take a ‘peek under the hood’ of Computer Vision and Deep Learning, sharing technology design principles and skill set profiles to consider before starting your CV journey.
Deep learning has matured considerably in the past few years to produce human or superhuman abilities in a variety of computer vision paradigms. We will discuss ways to recognize these paradigms in retail settings, collect and organize data to create actionable outcomes with the new insights and applications that deep learning enables.
We will cover the basics of object detection, then move into the advanced processing of images describing the possible ways that a retail store of the near future could operate. Identifying various storefront situations by having a deep learning system attached to a camera stream. Such things as; identifying item stocks on shelves, a shelf in need of organization, or perhaps a wandering customer in need of assistance.
We will also cover how to use a computer vision system to automatically track customer purchases to enable a streamlined checkout process, and how deep learning can power plausible wardrobe suggestions based on what a customer is currently wearing or purchasing.
Finally, we will cover the various technologies that are powering these applications today. Deep learning tools for research and development. Production tools to distribute that intelligence to an entire inventory of all the cameras situation around a retail location. Tools for exploring and understanding the new data streams produced by the computer vision systems.
By the end of this talk, attendees should understand the impact Computer Vision and Deep Learning are having in the Consumer Goods industry, key use cases, techniques and key considerations leaders are exploring and implementing today.
Big Data Genomics: Clustering Billions of DNA Sequences with Apache Spark
Whole genome shotgun based next generation transcriptomics and metagenomics studies often generate 100 to 1000 gigabytes (GB) sequence data derived from tens of thousands of different genes or microbial species. De novo assembling these data requires an ideal solution that both scales with data size and optimizes for individual gene or genomes. Here we developed an Apache Spark-based scalable sequence clustering application, SparkReadClust (SpaRC), that partitions the reads based on their molecule of origin to enable downstream assembly optimization. SpaRC produces high clustering performance on transcriptomics and metagenomics test datasets from both short read and long read sequencing technologies. It achieved a near linear scalability with respect to input data size and number of compute nodes. SpaRC can run on different cloud computing environments without modifications while delivering similar performance. In summary, our results suggest SpaRC provides a scalable solution for clustering billions of reads from the next-generation sequencing experiments, and Apache Spark represents a cost-effective solution with rapid development/deployment cycles for similar big data genomics problems.
