[jira] [Commented] (CHUKWA-649) To handle pid-file missing case
while stoping chukwa processes
[ https://issues.apache.org/jira/browse/CHUKWA-649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13416860#comment-13416860 ]
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?"

> 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.
