> Task containers can go over their resource limit, and killed by Node Manager.
> Then MR AM gets notified of the container status and diagnostics information
> through its heartbeat with RM. However, it is possible that the diagnostics
> information never gets into .jhist file, so when the job completes, the
> diagnostics information associated with the failed task attempts is empty.
> This makes it hard for users to root cause job failures that are often caused
> by memory leak.
