Savanna is an OpenStack project that provides tools for provisioning and managing Hadoop clusters on OpenStack. It allows users to easily run Hadoop jobs without expertise in Hadoop operations. Savanna provides an Elastic Data Processing (EDP) interface that hides cluster management and allows users to focus on their data and questions. The current version of Savanna supports various Hadoop distributions, integration with OpenStack services, and EDP features like executing Pig and Hive jobs. Future plans include further OpenStack integration and improvements to EDP.

Mission:
To provide the OpenStack community with an open,
cutting edge, performant and scalable data
processing stack and associated management
interfaces
● provision and operate Hadoop clusters
● schedule and operate Hadoop jobs

7. Use Cases
● Self-service provisioning of Hadoop clusters
● Utilization of unused compute capacity for
bursty workloads
● Run Hadoop workloads in few clicks without
expertise in Hadoop ops

13. EDP Overview
● End users have data and questions
○ The data lives in a data repository
○ The questions are embodied in code
● Savanna Elastic Data Processing (EDP) brings the
Hadoop ecosystem to the end user
○ Hides all cluster management behind the scenes

14. EDP
“Customers launch millions of
Amazon EMR clusters every
year.”

15. EDP
● Variety and depth of value add offerings on top of
clouds are growing
● Offerings are rarely open, rarely allow for choice
● Examples - Google Cloud, Azure, AWS

16. EDP
Savanna and EDP can both match and
exceed use cases provided by most
public clouds

17. EDP in Savanna v0.3
● UI, integrated into Horizon, for ad-hoc analytics
queries based on Hive or Pig
● API to execute MapReduce jobs without exposing
details of underlying infrastructure
● Pluggable data sources: Swift
● Supported job types: Jar, Pig, Hive
● Integration with Oozie for workflow management
