Ari Rabkin commented on CHUKWA-649:
-----------------------------------
I think it would be better to explicitly tell the user if there's nothing to
kill.
Possible wording: "No PID file found; not killing. Perhaps Chukwa was not
running?"
> To handle pid-file missing case while stoping chukwa processes

> If the pid-file is missing accidentally, the stop script will print out usage
> prompt of "kill" command. It is quite confused for the end user. The simple
> fix is to check that pid-file before executing kill command.
