> Project: Hadoop Map/Reduce

> This is to address the containers which exit properly after spawning
> sub-processes themselves. We don't want to leave these sub-process-tree or
> else they can pillage the NM's resources.
> Today, we already have code to send SIGKILL to the whole process-trees
> (because of single sessionId resulting from setsid) when the container is
> alive. We need to obtain the PID of the containers when they start and use
> that PID to send signal for completed containers' case also.
