> When YARN reports a completed container to the MR AM, it always interprets it
> as a failure. This can lead to a job failing because too many of its tasks
> failed, when in fact they only failed because the scheduler preempted them.
> MR needs to recognize the special exit code value of -100 and interpret it as
> a container being killed instead of a container failure.
