[jira] [Created] (MAPREDUCE-5718) MR AM should tolerate RM failover during commit

Karthik Kambatla created MAPREDUCE-5718:
-------------------------------------------

             Summary: MR AM should tolerate RM failover during commit
                 Key: MAPREDUCE-5718
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5718
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
    Affects Versions: 2.4.0
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla
            Priority: Blocker


While testing RM HA, we ran into this issue where if the RM fails over while an MR AM is in the middle of a commit, the subsequent AM gets spawned but dies with a diagnostic message - "We crashed durring a commit".
