> 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.
