Jason Lowe commented on MAPREDUCE-5465:
---------------------------------------

Sorry, I have been very busy as of late and haven't had time to get back to this patch.  I'll
try to get some review comments on the new patch posted by next week.

> If there is profiling enabled for mapper or reducer then hprof dumps profile.out at process
exit. It is dumped after task signaled to AM that work is finished.
> AM kills container with finished work without waiting for hprof to finish dumps. If hprof
is dumping larger outputs (such as with depth=4 while depth=3 works) , it could not finish
dump in time before being killed making entire dump unusable because cpu and heap stats are
missing.
> There needs to be better delay before container is killed if profiling is enabled.
