[jira] [Created] (MAPREDUCE-3312) Make MR AM not send a stopContainer w/o corresponding start container

Make MR AM not send a stopContainer w/o corresponding start container
---------------------------------------------------------------------

                 Key: MAPREDUCE-3312
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3312
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans
             Fix For: 0.23.0, 0.24.0


This is a follow on to MAPREDUCE-3274.  It is possible, although rare, for the MR AM to send a stop container before it sends a start container.  This needs to stop that from happening.  If a stop is found first it should prevent the start from being sent.  It tries to do this, but only if the stop is currently pending.
