The new name of the Elastic Hadoop on OpenStack project is Savanna. This pages are obsolete and latest info is located at launchpad.net/savanna

Savanna project aims to provide users with simple means to provision a Hadoop cluster by specifying several parameters like Hadoop version, cluster topology, nodes hardware details and a few more. After user fills in all the parameters, Savanna deploys the cluster in a few minutes. Also Savanna provides means to scale already provisioned cluster by adding/removing worker nodes on demand.

The solution will address following use cases:
- fast provisioning of Hadoop clusters on OpenStack for Dev and QA;
- utilization of unused compute power from general purpose OpenStack IaaS cloud;
- “Analytics as a Service” for ad-hoc or bursty analytic workloads (similar to AWS EMR).
