Jean-Daniel Cryans commented on HBASE-6970:
-------------------------------------------

lol I'm looking at the same problem and worrying about the same thing. At least 
changing this behavior would help things like supervisord.
                
> hbase-deamon.sh creates/updates pid file even when that start failed.

> The problem is this:

>     nohup nice -n $HBASE_NICENESS "$HBASE_HOME"/bin/hbase \
>         --config "${HBASE_CONF_DIR}" \
>         $command "$@" $startStop > "$logout" 2>&1 < /dev/null &
>     echo $! > $pid
> {code}
> So the pid file is create or update even the start of the service failed. The 
> next stop command will then fail, because the pid file has he wrong pid in it.
