Ambari talk at Hadoop Summit, Tokyo 2016
Abstract
Apache Ambari has become an indispensable tool for operating Hadoop clusters from as small as 10s of nodes to 1000s of nodes. Ambari’s deep knowledge of the Hadoop stack allows it to deploy a cluster within minutes and manage the entire lifecycle: scaling, security, upgrades, and more. This talk will cover the central features important to cluster operators and the latest innovations from the community. We will discuss automatically deploying clusters with Blueprints, adding custom services, scaling the number of hosts as the data needs grow, adding High Availability for critical services, securing with MIT kerberos, and upgrading the Hadoop stack with features like Rolling & Express Upgrade. More advanced users will also be interested in using Ambari’s powerful REST API to automate workflows. For users and data scientists, Ambari provides LDAP sync, Role-Based Access Control to handle user permissions, and a framework to host Ambari Views such as as the newly added Views for Hive, Oozie, Capacity Scheduler, Tez, Storm, and Zeppelin. Lastly, we will cover how to monitor the health of the cluster via Alerts and troubleshoot problems by using new features like LogSearch and Ambari Metrics Systems integrated with Grafana UI.

Manage Add-on Services in Apache AmbariJayush Luniya
Cutting-edge Hadoop clusters are bound to need custom (add-on) services that are not available in the Hadoop distribution of their choice. Agility is crucial for companies to integrate any service into existing large-scale Hadoop clusters with ease.
Apache Ambari manages the Hadoop cluster and solves this problem by extending the stack with add-on services, which can be a new Apache project, different Hadoop file system, or internal tool. This talk covers how to create a service definition in Ambari to manage lifecycle commands and configs, plus advanced topics like packaging, installing from multiple repositories, recommending and validating configs using Service Advisor, running custom commands, defining dependencies on configs and other services, and more. We will also cover how to create custom metrics and dashboards using Ambari Metric System and Grafana, generating alerts, and enabling security by authenticating with Kerberos.
Further, we will discuss the future of service definitions and how Ambari 3.0 will support custom services through Management Packs to enable Hadoop vendors to release software faster.
Apache Ambari is a single framework for IT administrators to provision, manage and monitor a Hadoop cluster. Apache Ambari 1.7.0 is included with Hortonworks Data Platform 2.2.
In this 30-minute webinar, Hortonworks Product Manager Jeff Sposetti and Apache Ambari committer Mahadev Konar discussed new capabilities including:
Improvements to Ambari core - such as support for ResourceManager HA
Extensions to Ambari platform - introducing Ambari Administration and Ambari Views
Enhancements to Ambari Stacks - dynamic configuration recommendations and validations via a "Stack Advisor"

Tuning Apache Ambari performance for Big Data at scale with 3000 agentsDataWorks Summit
Apache Ambari manages Hadoop at large-scale and it becomes increasingly difficult for cluster admins to keep the machinery running smoothly as data grows and nodes scale from 30 to 3000 agents. To test at scale, Ambari has a Performance Stack that allows a VM to host as many as 50 Ambari Agents. The simulated stack and 50 Agents per VM can stress-test Ambari Server with the same load as a 3000 node cluster. This talk will cover how to tune the performance of Ambari and MySQL, and share performance benchmarks for features like deploy times, bulk operations, installation of bits, Rolling & Express Upgrade. Moreover, the speaker will show how to use Ambari Metrics System and Grafana to plot performance, detect anomalies, and pinpoint tips on how to improve performance for a more responsive experience. Lastly, the talk will discuss roadmap features in Ambari 3.0 for improving performance and scale.

Apache Druid Auto Scale-out/in for Streaming Data Ingestion on KubernetesDataWorks Summit
The importance of ingestion and processing streaming data in telecommunication industry is ever increasing. We, SK Telecom which is Korea's number-one telecommunications provider, encounter how to use infra resources more efficiently. Apache Druid supports auto scaling feature for data ingestion, but it is only available on AWS EC2. We cannot rely on the feature on our private cloud.
In this talk, we are going to introduce auto scale-out/in on Kubernetes. This approach is more outstanding than Druid's scaling implementation. Here are the benefits. The first is our approach can be used anywhere on private cloud or (managed) Kubernetes in Azure, AWS and GKE. The second is AWS EC2's startup and termination requires a few minutes, but our approach requires a few seconds. The last is the scaling mechanism is decoupled from Druid's source code. We will also share development of Druid Helm chart, rolling update, custom metric usage for horizontal auto scaling.
The below is about detailed benefit compared with Druid's auto scaling approach:
1. Druid's auto scaling is only available in AWS, but our approach does not have the obstacle. It can be used in Private cloud(on-premise) are (managed) Kubernetes in Azure, AWS and GKE.
2. AWS EC2 is an instance of virtual machine, so the startup is slower than docker container. A few minutes are required for startup or termination of EC2. Docker container is very lightweight, so it requires a few seconds.
3. Druid's auto scaling is tightly coupled with AWS API because Druid engine code uses AWS API. Our scale-out/in algorithm is conceptually equal to Druid's auto scaling approach, but we decoupled the dependency because Kubernetes communicate with one of dispatcher nodes(i.e. Overlord node) using REST API.
Ansible is the simplest way to automate. MoldCamp, 2015Alex S
Ansible is a radically simple IT automation engine. This is new and great configuration management system (like Chef, Puppet) that has been created in 2012 year. Also Ansible is pretty simple and flexible system, that helps you in managing your servers and execute Ad-hoc commands.
During this session I will explain how to start using Ansible in infrastructure orchestration and what are pros and cons of this system. Also I will explain you our experience in deployments, provisioning and other aspects.
Capacity planning is a difficult challenge faced by most companies. If you have too few machines, you will not have enough compute resources available to deal with heavy loads. On the other hand, if you have too many machines, you are wasting money. This is why companies have started investing in automatically scaling services and infrastructure to minimize the amount of wasted money and resources.
In this talk, Nathan will describe how Yelp is using PaaSTA, a PaaS built on top of open source tools including Docker, Mesos, Marathon, and Chronos, to automatically and gracefully scale services and the underlying cluster. He will go into detail about how this functionality was implemented and the design designs that were made while architecting the system. He will also provide a brief comparison of how this approach differs from existing solutions.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Cluster install takes 5-10 mins, mostly downloading packages, installing bits, and starting services.
Used by HDInsight (Microsoft Azure) and Hortonworks QA
Allow cluster creation or scaling to be started via the REST API prior to all/any hosts being available. As hosts register with Ambari server they will be matched to request host groups and provisioned according to the requested topology
Allow host predicates to be specified along with host count to provide more flexibility in matching hosts to host groups. This will allow for host flavors where different host groups are matched to different host flavors
Break up the current monolithic provisioning request into a request for each host operation. For example, install on host A, start on host A, install on hostB, etc. This will allow hosts to make progress even when another host encounters a failure.
Allow a host count to be specified in the cluster creation template instead of host names. This is documented in https://issues.apache.org/jira/browse/AMBARI-6275
Install a cluster with two API calls
The blueprint contains the configs, assignment of topology to host group, stack version
The creation actually assigns hosts to each host group.

Dynamic availability
Allow host_count to be specified instead of host_namesAs hosts register, they will be matched to the request host groups and provisioned according to to the requested topology
When specifying a host_count, a predicate can also be specified for finer-grained control

As Ambari grows and organizations grow, so do security needs
Users have fine-grained roles over the cluster and individual views.
Granular authorization checks to distribute the responsibilities and privileges of authenticated users
