1 Savanna Hadoop on OpenStack Sergey Lukjanov Savanna Technical Lead Mirantis, 2013

2 Agenda Savanna Overview Savanna Use Cases Roadmap & Current Status Architecture & Features Overview Hadoop vs. Virtualization

3 Agenda Savanna Overview Savanna Use Cases Roadmap & Current Status Architecture & Features Overview Hadoop vs. Virtualization

4 Savanna - Elastic Hadoop on OpenStack Open source native OpenStack component Supports different Hadoop distributions Solves both bare cluster provisioning use case and "analytics as a service" Managed through REST API Web UI as part of the OpenStack Dashboard Flexible templates of Hadoop configurations

5 Savanna - Elastic Hadoop on OpenStack Project home - bug tracking blueprints answers Code review (gerrit) - Sources - Mailing list - savanna-all@lists.launchpad.net CI - and

6 Savanna - Participants Contributors: large core team from Mirantis teams from RedHat, Hortonworks several minor contributors Intel joined recently Several upcoming customers

7 Agenda Savanna Overview Savanna Use Cases Roadmap & Current Status Architecture & Features Overview Hadoop vs. Virtualization

8 Savanna Use Cases Administrators - centralized cluster management and monitoring Dev and QA teams - fast clusters provisioning Data Scientists/Analysts - API to run the analytic jobs with infrastructure provisioning happening under the hood Making resources dedicated to IaaS cloud available for Hadoop workload

9 Administrators Use Case Central point of control over infrastructure Enables self-service capabilities, including choice of Hadoop distribution to be used Integration with vendor tooling: Ambari for Apache/HortonWorks Cloudera Management Console Intel Hadoop Utilization of free IaaS capacity for Hadoop tasks

10 Dev and QA Use Cases Fast on-demand provisioning of the environments Increase agility and speed of innovation Controlled access to data from production

11 Analytics Use Cases Simplified tasks execution - complexity of provisioning and managing cluster hidden under the hood Access to higher level interfaces (e.g. pig, hive) Bursty workload: ad-hoc queries requiring a significant resource only for short time period Utilization of free IaaS capacity for Hadoop tasks

12 Agenda Savanna Overview Savanna Use Cases Roadmap & Current Status Architecture & Features Overview Hadoop vs. Virtualization

13 Roadmap for Hadoop in Cloud Phase 1 Basic cluster provisioning of Apache Hadoop Phase 2 Cluster operation support and integration with tooling, advanced configuration (HDFS, Swift, etc.) Phase 3 "Analytics as a service": job execution framework, support different scripting languages, deeper integration with OS

14 Phase 1 - Basic Cluster Operation Cluster provisioning Deployment Engine implementation for preinstalled images Templates for Hadoop cluster configuration REST API for cluster startup and operations Web UI integrated into OpenStack Dashboard

15 Roadmap for Hadoop in Cloud Phase 1 [Released - April, 10] Basic cluster provisioning of Apache Hadoop Phase 2 Cluster operation support and integration with tooling, advanced configuration (HDFS, Swift, etc.) Phase 3 "Analytics as a service": job execution framework, support different scripting languages, deeper integration with OS

16 Phase 2 - Advanced Configuration Hadoop cluster configuration support: Solutions for HDFS data reliability issue Configurable storage location Configurable topology of, NN, TT, JT Add/remove nodes More Hadoop parameters Integration with vendor deployment/management tooling Basic monitoring support

17 Roadmap for Hadoop in Cloud Phase 1 [Released - April, 10] Basic cluster provisioning of Apache Hadoop Phase 2 [In progress - July 15] Cluster operation support and integration with tooling, advanced configuration (HDFS, Swift, etc.) Phase 3 "Analytics as a service": job execution framework, support different scripting languages, deeper integration with OS

18 Phase 3 - Analytics as a Service API to execute Map/Reduce jobs without exposing details of underlying infrastructure (similar to AWS EMR) User-friendly UI for ad-hoc analytics queries based on Hive or Pig

19 Roadmap for Hadoop in Cloud Phase 1 [Released - April, 10] Basic cluster provisioning of Apache Hadoop Phase 2 [In progress - July 15] Cluster operation support and integration with tooling, advanced configuration (HDFS, Swift, etc.) Phase 3 [Planned - October 15] "Analytics as a service": job execution framework, support different scripting languages, deeper integration with OS

20 Further Roadmap Autoscaling HA for NameNode Deeper HDFS and Swift integration Caching of Swift data on HDFS Integration with logging and error handling HBase support
