It summarizes that Amazon uses Spark and Zeppelin notebooks to allow data scientists to develop queries in an agile manner. Deep learning jobs are run on GPUs using Amazon ECS, while CPU jobs run on Amazon EMR. DSSTNE is optimized for large sparse neural networks and allows defining networks in a human-readable JSON format to efficiently handle Amazon's large recommendation problems.
Let Spark Fly: Advantages and Use Cases for Spark on HadoopMapR Technologies
http://bit.ly/1BTaXZP – Apache Spark is currently one of the most active projects in the Hadoop ecosystem, and as such, there’s been plenty of hype about it in recent months, but how much of the discussion is marketing spin? And what are the facts? MapR and Databricks, the company that created and led the development of the Spark stack, will cut through the noise to uncover practical advantages for having the full set of Spark technologies at your disposal and reveal the benefits for running Spark on Hadoop
This presentation was given at a webinar hosted by Data Science Central and co-presented by MapR + Databricks.
To see the webinar, please go to: http://www.datasciencecentral.com/video/let-spark-fly-advantages-and-use-cases-for-spark-on-hadoop
http://bit.ly/1BTaXZP – Hadoop has been a huge success in the data world. It’s disrupted decades of data management practices and technologies by introducing a massively parallel processing framework. The community and the development of all the Open Source components pushed Hadoop to where it is now.
That's why the Hadoop community is excited about Apache Spark. The Spark software stack includes a core data-processing engine, an interface for interactive querying, Sparkstreaming for streaming data analysis, and growing libraries for machine-learning and graph analysis. Spark is quickly establishing itself as a leading environment for doing fast, iterative in-memory and streaming analysis.
This talk will give an introduction the Spark stack, explain how Spark has lighting fast results, and how it complements Apache Hadoop.

Experience of Running Spark on Kubernetes on OpenStack for High Energy Physic...Databricks
The physicists at CERN are increasingly turning to Spark to process large physics datasets in a distributed fashion with the aim of reducing time-to-physics with increased interactivity. The physics data itself is stored in CERN’s mass storage system: EOS and CERN’s IT department runs on-premise private cloud based on OpenStack as a way to provide on-demand compute resources to physicists. This provides both opportunity and challenges to Big Data team at CERN to provide elastic, scalable, reliable spark-as-a-service on OpenStack.
The talk focuses on the design choices made and challenges faced while developing spark-as-a-service over kubernetes on openstack to simplify provisioning, automate management, and minimize the operating burden of managing Spark Clusters. In addition, the service tooling simplifies submitting applications on the behalf of the users, mounting user-specified ConfigMaps, copying application logs to s3 buckets for troubleshooting, performance analysis and accounting of spark applications and support for stateful spark streaming applications. We will also share results from running large scale sustained workloads over terabytes of physics data.
Deep Learning Pipelines for High Energy Physics using Apache Spark with Distr...Databricks
You will learn how CERN has implemented an Apache Spark-based data pipeline to support deep learning research work in High Energy Physics (HEP). HEP is a data-intensive domain. For example, the amount of data flowing through the online systems at LHC experiments is currently of the order of 1 PB/s, with particle collision events happening every 25 ns. Filtering is applied before storing data for later processing.
Improvements in the accuracy of the online event filtering system are key to optimize usage and cost of compute and storage resources. A novel prototype of event filtering system based on a classifier trained using deep neural networks has recently been proposed. This presentation covers how we implemented the data pipeline to train the neural network classifier using solutions from the Apache Spark and Big Data ecosystem, integrated with tools, software, and platforms familiar to scientists and data engineers at CERN. Data preparation and feature engineering make use of PySpark, Spark SQL and Python code run via Jupyter notebooks.
We will discuss key integrations and libraries that make Apache Spark able to ingest data stored using HEP data format (ROOT) and the integration with CERN storage and compute systems. You will learn about the neural network models used, defined using the Keras API, and how the models have been trained in a distributed fashion on Spark clusters using BigDL and Analytics Zoo. We will discuss the implementation and results of the distributed training, as well as the lessons learned.
Kerberizing Spark: Spark Summit East talk by Abel Rincon and Jorge Lopez-MallaSpark Summit
Spark had been elected, deservedly, as the main massive parallel processing framework, and HDFS is the one of the most popular Big Data storage technologies. Therefore its combination is one of the most usual Big Data’s use cases. But, what happens with the security? Can these two technologies coexist in a secure environment? Furthermore, with the proliferation of BI technologies adapted to Big Data environments, that demands that several users interacts with the same cluster concurrently, can we continue to ensure that our Big Data environments are still secure? In this lecture, Abel and Jorge will explain which adaptations of Spark´s core they had to perform in order to guarantee the security of multiple concurrent users using a single Spark cluster, which can use any of its cluster managers, without degrading the outstanding Spark’s performance.
Integrating Existing C++ Libraries into PySpark with Esther KundinDatabricks
Bloomberg’s Machine Learning/Text Analysis team has developed many machine learning libraries for fast real-time sentiment analysis of incoming news stories. These models were developed using smaller training sets, implemented in C++ for minimal latency, and are currently running in production. To facilitate backtesting our production models across our full data set, we needed to be able to parallelize our workloads, while using the actual production code.
We also wanted to integrate the C++ code with PySpark and use it to run our models. In this talk, I will discuss some of the challenges we faced, decisions we made, and other options when dealing with integrating existing C++ code into a Spark system. The techniques we developed have been used successfully by our team multiple times and I am sure others will benefit from the gotchas that we were able to identify.
Cosmos DB Real-time Advanced Analytics WorkshopDatabricks
The workshop implements an innovative fraud detection solution as a PoC for a bank who provides payment processing services for commerce to their merchant customers all across the globe, helping them save costs by applying machine learning and advanced analytics to detect fraudulent transactions. Since their customers are around the world, the right solutions should minimize any latencies experienced using their service by distributing as much of the solution as possible, as closely as possible, to the regions in which their customers use the service. The workshop designs a data pipeline solution that leverages Cosmos DB for both the scalable ingest of streaming data, and the globally distributed serving of both pre-scored data and machine learning models. Cosmos DB’s major advantage when operating at a global scale is its high concurrency with low latency and predictable results.
This combination is unique to Cosmos DB and ideal for the bank needs. The solution leverages the Cosmos DB change data feed in concert with the Azure Databricks Delta and Spark capabilities to enable a modern data warehouse solution that can be used to create risk reduction solutions for scoring transactions for fraud in an offline, batch approach and in a near real-time, request/response approach. https://github.com/Microsoft/MCW-Cosmos-DB-Real-Time-Advanced-Analytics Takeaway: How to leverage Azure Cosmos DB + Azure Databricks along with Spark ML for building innovative advanced analytics pipelines.
Serverless Machine Learning on Modern Hardware Using Apache Spark with Patric...Databricks
Recently, there has been increased interest in running analytics and machine learning workloads on top of serverless frameworks in the cloud. The serverless execution model provides fine-grained scaling and unburdens users from having to manage servers, but also adds substantial performance overheads due to the fact that all data and intermediate state of compute task is stored on remote shared storage.
In this talk I first provide a detailed performance breakdown from a machine learning workload using Spark on AWS Lambda. I show how the intermediate state of tasks — such as model updates or broadcast messages — is exchanged using remote storage and what the performance overheads are. Later, I illustrate how the same workload performs on-premise using Apache Spark and Apache Crail deployed on a high-performance cluster (100Gbps network, NVMe Flash, etc.). Serverless computing simplifies the deployment of machine learning applications. The talk shows that performance does not need to be sacrificed.
Apache Spark 2.4 Bridges the Gap Between Big Data and Deep LearningDataWorks Summit
Big data and AI are joined at the hip: AI applications require massive amounts of training data to build state-of-the-art models. The problem is, big data frameworks like Apache Spark and distributed deep learning frameworks like TensorFlow don’t play well together due to the disparity between how big data jobs are executed and how deep learning jobs are executed.
Apache Spark 2.4 introduced a new scheduling primitive: barrier scheduling. User can indicate Spark whether it should be using the MapReduce mode or barrier mode at each stage of the pipeline, thus it’s easy to embed distributed deep learning training as a Spark stage to simplify the training workflow. In this talk, I will demonstrate how to build a real case pipeline which combines data processing with Spark and deep learning training with TensorFlow step by step. I will also share the best practices and hands-on experiences to show the power of this new features, and bring more discussion on this topic.

Building a Dataset Search Engine with Spark and Elasticsearch: Spark Summit E...Spark Summit
Elasticsearch provides native integration with Apache Spark through ES-Hadoop. However, especially during development, it is at best cumbersome to have Elasticsearch running in a separate machine/instance. Leveraging Spark Cluster with Elasticsearch Inside it is possible to run an embedded instance of Elasticsearch in the driver node of a Spark Cluster. This opens up new opportunities to develop cutting-edge applications. One such application is Dataset Search.
Oscar will give a demo of a Dataset Search Engine built on Spark Cluster with Elasticsearch Inside. Motivation is that once Elasticsearch is running on Spark it becomes possible and interesting to have the Elasticsearch in-memory instance join an (existing) Elasticsearch cluster. And this in turn enables indexing of Datasets that are processed as part of Data Pipelines running on Spark. Dataset Search and Data Management are R&D topics that should be of interest to Spark Summit East attendees who are looking for a way to organize their Data Lake and make it searchable.

Similar to Generating Recommendations at Amazon Scale with Apache Spark and Amazon DSSTNE (20)
Many Organizations are currently processing various types of data and in different formats. Most often this data will be in free form, As the consumers of this data growing it’s imperative that this free-flowing data needs to adhere to a schema. It will help data consumers to have an expectation of about the type of data they are getting and also they will be able to avoid immediate impact if the upstream source changes its format. Having a uniform schema representation also gives the Data Pipeline a really easy way to integrate and support various systems that use different data formats.
SchemaRegistry is a central repository for storing, evolving schemas. It provides an API & tooling to help developers and users to register a schema and consume that schema without having any impact if the schema changed. Users can tag different schemas and versions, register for notifications of schema changes with versions etc.
In this talk, we will go through the need for a schema registry and schema evolution and showcase the integration with Apache NiFi, Apache Kafka, Apache Storm.
There is increasing need for large-scale recommendation systems. Typical solutions rely on periodically retrained batch algorithms, but for massive amounts of data, training a new model could take hours. This is a problem when the model needs to be more up-to-date. For example, when recommending TV programs while they are being transmitted the model should take into consideration users who watch a program at that time.
The promise of online recommendation systems is fast adaptation to changes, but methods of online machine learning from streams is commonly believed to be more restricted and hence less accurate than batch trained models. Combining batch and online learning could lead to a quickly adapting recommendation system with increased accuracy. However, designing a scalable data system for uniting batch and online recommendation algorithms is a challenging task. In this talk we present our experiences in creating such a recommendation engine with Apache Flink and Apache Spark.
DeepLearning is not just a hype - it outperforms state-of-the-art ML algorithms. One by one. In this talk we will show how DeepLearning can be used for detecting anomalies on IoT sensor data streams at high speed using DeepLearning4J on top of different BigData engines like ApacheSpark and ApacheFlink. Key in this talk is the absence of any large training corpus since we are using unsupervised machine learning - a domain current DL research threats step-motherly. As we can see in this demo LSTM networks can learn very complex system behavior - in this case data coming from a physical model simulating bearing vibration data. Once draw back of DeepLearning is that normally a very large labaled training data set is required. This is particularly interesting since we can show how unsupervised machine learning can be used in conjunction with DeepLearning - no labeled data set is necessary. We are able to detect anomalies and predict braking bearings with 10 fold confidence. All examples and all code will be made publicly available and open sources. Only open source components are used.
QE automation for large systems is a great step forward in increasing system reliability. In the big-data world, multiple components have to come together to provide end-users with business outcomes. This means, that QE Automations scenarios need to be detailed around actual use cases, cross-cutting components. The system tests potentially generate large amounts of data on a recurring basis, verifying which is a tedious job. Given the multiple levels of indirection, the false positives of actual defects are higher, and are generally wasteful.
At Hortonworks, we’ve designed and implemented Automated Log Analysis System - Mool, using Statistical Data Science and ML. Currently the work in progress has a batch data pipeline with a following ensemble ML pipeline which feeds into the recommendation engine. The system identifies the root cause of test failures, by correlating the failing test cases, with current and historical error records, to identify root cause of errors across multiple components. The system works in unsupervised mode with no perfect model/stable builds/source-code version to refer to. In addition the system provides limited recommendations to file/open past tickets and compares run-profiles with past runs.
Improving business performance is never easy! The Natixis Pack is like Rugby. Working together is key to scrum success. Our data journey would undoubtedly have been so much more difficult if we had not made the move together.
This session is the story of how ‘The Natixis Pack’ has driven change in its current IT architecture so that legacy systems can leverage some of the many components in Hortonworks Data Platform in order to improve the performance of business applications. During this session, you will hear:
• How and why the business and IT requirements originated
• How we leverage the platform to fulfill security and production requirements
• How we organize a community to:
o Guard all the players, no one gets left on the ground!
o Us the platform appropriately (Not every problem is eligible for Big Data and standard databases are not dead)
• What are the most usable, the most interesting and the most promising technologies in the Apache Hadoop community
We will finish the story of a successful rugby team with insight into the special skills needed from each player to win the match!
DETAILS
This session is part business, part technical. We will talk about infrastructure, security and project management as well as the industrial usage of Hive, HBase, Kafka, and Spark within an industrial Corporate and Investment Bank environment, framed by regulatory constraints.
HBase hast established itself as the backend for many operational and interactive use-cases, powering well-known services that support millions of users and thousands of concurrent requests. In terms of features HBase has come a long way, overing advanced options such as multi-level caching on- and off-heap, pluggable request handling, fast recovery options such as region replicas, table snapshots for data governance, tuneable write-ahead logging and so on. This talk is based on the research for the an upcoming second release of the speakers HBase book, correlated with the practical experience in medium to large HBase projects around the world. You will learn how to plan for HBase, starting with the selection of the matching use-cases, to determining the number of servers needed, leading into performance tuning options. There is no reason to be afraid of using HBase, but knowing its basic premises and technical choices will make using it much more successful. You will also learn about many of the new features of HBase up to version 1.3, and where they are applicable.
There has been an explosion of data digitising our physical world – from cameras, environmental sensors and embedded devices, right down to the phones in our pockets. Which means that, now, companies have new ways to transform their businesses – both operationally, and through their products and services – by leveraging this data and applying fresh analytical techniques to make sense of it. But are they ready? The answer is “no” in most cases.
In this session, we’ll be discussing the challenges facing companies trying to embrace the Analytics of Things, and how Teradata has helped customers work through and turn those challenges to their advantage.
In this talk, we will present a new distribution of Hadoop, Hops, that can scale the Hadoop Filesystem (HDFS) by 16X, from 70K ops/s to 1.2 million ops/s on Spotiy's industrial Hadoop workload. Hops is an open-source distribution of Apache Hadoop that supports distributed metadata for HSFS (HopsFS) and the ResourceManager in Apache YARN. HopsFS is the first production-grade distributed hierarchical filesystem to store its metadata normalized in an in-memory, shared nothing database. For YARN, we will discuss optimizations that enable 2X throughput increases for the Capacity scheduler, enabling scalability to clusters with >20K nodes. We will discuss the journey of how we reached this milestone, discussing some of the challenges involved in efficiently and safely mapping hierarchical filesystem metadata state and operations onto a shared-nothing, in-memory database. We will also discuss the key database features needed for extreme scaling, such as multi-partition transactions, partition-pruned index scans, distribution-aware transactions, and the streaming changelog API. Hops (www.hops.io) is Apache-licensed open-source and supports a pluggable database backend for distributed metadata, although it currently only support MySQL Cluster as a backend. Hops opens up the potential for new directions for Hadoop when metadata is available for tinkering in a mature relational database.
In high-risk manufacturing industries, regulatory bodies stipulate continuous monitoring and documentation of critical product attributes and process parameters. On the other hand, sensor data coming from production processes can be used to gain deeper insights into optimization potentials. By establishing a central production data lake based on Hadoop and using Talend Data Fabric as a basis for a unified architecture, the German pharmaceutical company HERMES Arzneimittel was able to cater to compliance requirements as well as unlock new business opportunities, enabling use cases like predictive maintenance, predictive quality assurance or open world analytics. Learn how the Talend Data Fabric enabled HERMES Arzneimittel to become data-driven and transform Big Data projects from challenging, hard to maintain hand-coding jobs to repeatable, future-proof integration designs.
Talend Data Fabric combines Talend products into a common set of powerful, easy-to-use tools for any integration style: real-time or batch, big data or master data management, on-premises or in the cloud.
While you could be tempted assuming data is already safe in a single Hadoop cluster, in practice you have to plan for more. Questions like: "What happens if the entire datacenter fails?, or "How do I recover into a consistent state of data, so that applications can continue to run?" are not a all trivial to answer for Hadoop. Did you know that HDFS snapshots are handling open files not as immutable? Or that HBase snapshots are executed asynchronously across servers and therefore cannot guarantee atomicity for cross region updates (which includes tables)? There is no unified and coherent data backup strategy, nor is there tooling available for many of the included components to build such a strategy. The Hadoop distributions largely avoid this topic as most customers are still in the "single use-case" or PoC phase, where data governance as far as backup and disaster recovery (BDR) is concerned are not (yet) important. This talk first is introducing you to the overarching issue and difficulties of backup and data safety, looking at each of the many components in Hadoop, including HDFS, HBase, YARN, Oozie, the management components and so on, to finally show you a viable approach using built-in tools. You will also learn not to take this topic lightheartedly and what is needed to implement and guarantee a continuous operation of Hadoop cluster based solutions.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

8. This Is A Huge Sparse Data Problem
l Uncompressed sparse data either eats a lot of memory
or it eats a lot of bandwidth uploading it to the GPU
l Naively running networks with uncompressed sparse
data leads to lots of multiplications of zero by zero. This
wastes memory, power, and time
l Product Recommendation Networks can have billions of
parameters that cannot fit in a single GPU so
