> When an AM attempt expires the AMLivelinessMonitor in the RM will kill the job and mark
it as failed.  However there are no diagnostic messages set for the application indicating
that the application failed because of expiration.  Even if the AM logs are examined, it's
often not obvious that the application was externally killed.  The only evidence of what happened
to the application is currently in the RM logs, and those are often not accessible by users.
