> 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.
