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.
