    Description

      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.
