------------------------------------

Hi,

I'm using Apache Cassandra 3.0.13 version.

I'm facing a problem when stopping Cassandra service.

when stopping Cassandra service,it is not stopping and process is still running in the background.

 !screenshot-1.png! 

it is throwing a error message in log as below.

My Cassandra service stop script in /etc/rc.d/init.d/cassandra file is as below.

please let me know if any of you had faced the same problem and what is the cause for this issue.

Thanks in advance!!

Bhargav.

> 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}
