--------------------------------------------------

             Summary: MR AM doesn't handle exceptions from RM correctly
                 Key: MAPREDUCE-4761
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4761
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster
            Reporter: Vinod Kumar Vavilapalli


The MR AM currently ignores exceptions upto a certain count irrespective of the failure type.

Exception handling on the MR AM side is totally broken, it doesn't seem to shutdown the AM
on getting critical exceptions or reboot commands from the RM - another bug.
