Subject [jira] [Commented] (FALCON-442) overwriting of PID while multiple falcon start
Date Sun, 17 Jan 2016 16:47:39 GMT

    [ https://issues.apache.org/jira/browse/FALCON-442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15103784#comment-15103784
] 

Deepak Barr commented on FALCON-442:
------------------------------------

One possibility that can cause this issue - 

1. Run falcon-start
2. remove falcon.pid from $FALCON_HOME/logs directory
3. Run falcon-start again. This command will not be able to start to falcon server but will
create falcon.pid with new PID.
4. Now, if you do falcon-stop. It will try to stop the PID in falcon.pid resulting in "No
such process" error". 

Not sure if falcon.pid was removed ( step 2) before starting falcon again when samarth saw
this issue.

> if falcon-start command is run on a already running falcon server, it goes and updates
the PID that was stored during the previous falcon-star, however falcon keep running with
the original PID.  
> Due to this , when falcon-stop is run we get a missing process error, similar to below.

> {code}
> /usr/lib/falcon/falconServer/bin/service-stop.sh: line 36: kill: (19518) - No such process
> {code}
