> Sometimes I do {{/etc/init.d/cassandra stop}} and it prints out OK, but the server is
still running.  (This happens, for example, if it's busy doing GCs.)  The current init script
prints out OK after sleeping but without checking if the process really stopped. I suggest
changing it to:
> {noformat}
> pd0-cassandra16 ~> diff -C 1 cassandra cassandra-original
> *** cassandra   2015-02-04 09:15:58.088209988 -0800
> --- cassandra-original  2015-02-04 09:15:40.293767501 -0800
> ***************
> *** 69,77 ****
>           sleep 5
> !         THE_STATUS=`$0 status`
> !         if [[ $THE_STATUS == *"stopped"* ]]
> !         then
> !            echo "OK"
> !         else
> !            echo "ERROR: could not stop the process: $THE_STATUS"
> !            exit 1
> !         fi
>           ;;
> --- 69,71 ----
>           sleep 5
> !         echo "OK"
>           ;;
> {noformat}
> Then it prints out OK only if the stop succeeded. Otherwise it prints out a message like
> {quote}
> ERROR: could not stop the process: cassandra (pid  10764) is running...
> {quote}
