-------------------------------------
Summary: History server leveldb recovery store
Key: MAPREDUCE-6141
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6141
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: jobhistoryserver
Reporter: Jason Lowe
Assignee: Jason Lowe
It would be nice to have a leveldb option to the job history server 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.
