OutputCommitter changes for MR Application Master recovery
----------------------------------------------------------
Key: MAPREDUCE-2702
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2702
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: mrv2
Reporter: Sharad Agarwal
Assignee: Sharad Agarwal
In MR AM recovers from a crash, it only reruns the non completed tasks. The
completed tasks (along with their output, if any) needs to be recovered from
the previous life. This would require some changes in OutputCommitter.
