----------------------------------------
Hi [~eyang], process_with_sigterm_trap.sh is missing in the commit. Would you fix it?

> I'm seeing that sometimes daemons keep running for a little while even after "kill -9" from daemon-stop scripts.
> Debugging more, I see several instances of "ERROR: Unable to kill ${pid}".
> Saw this specifically with ResourceManager & NodeManager - {{yarn --daemon stop nodemanager}}. Though it is possible that other daemons may run into this too.
> Saw this on both Centos as well as Ubuntu.
