[jira] [Created] (MAPREDUCE-4901) JobHistoryEventHandler errors should be fatal

Robert Joseph Evans created MAPREDUCE-4901:
----------------------------------------------

             Summary: JobHistoryEventHandler errors should be fatal
                 Key: MAPREDUCE-4901
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4901
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.0.0-alpha, 0.23.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


To be able to truly fix issues like MAPREDUCE-4819 and MAPREDUCE-4832, we need a 2 phase commit where a subsequent AM can be sure that at a specific point in time it knows exactly if any tasks/jobs are committing.  The job history log is already used for similar functionality so we would like to reuse this, but we need to be sure that errors while writing out to the job history log are now fatal.
