Donald Smith commented on CASSANDRA-8738:
-----------------------------------------
Here's the change in context:
{noformat}
stop)
# Cassandra shutdown
echo -n "Shutdown Cassandra: "
su $CASSANDRA_OWNR -c "kill `cat $pid_file`"
for t in `seq 40`; do $0 status > /dev/null 2>&1 && sleep 0.5 || break;
done
# Adding a sleep here to give jmx time to wind down (CASSANDRA-4483).
Not ideal...
# Adam Holmberg suggests this, but that would break if the jmx port is
changed
# for t in `seq 40`; do netstat -tnlp | grep "0.0.0.0:7199" > /dev/null
2>&1 && sleep 0.1 || break; done
sleep 5
THE_STATUS=`$0 status`
if [[ $THE_STATUS == *"stopped"* ]]
then
echo "OK"
else
echo "ERROR: could not stop the process: $THE_STATUS"
fi
;;
{noformat}
> "/etc/init.d/cassandra stop" prints OK even when it doesn't work

> 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

> Then it prints out OK only if the stop succeeded. Otherwise it prints out a
> message like
