> 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.
