             Summary: Add leveldb-based implementation for RMStateStore
                 Key: YARN-2765
                 URL: https://issues.apache.org/jira/browse/YARN-2765
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Jason Lowe
            Assignee: Jason Lowe

It would be nice to have a leveldb option to the resourcemanager recovery 
store. Leveldb would provide some benefits over the existing filesystem store 
such as better support for atomic operations, fewer I/O ops per state update, 
and far fewer total files on the filesystem.
