Major Description
In ranger usersync and tagsync scripts, stop of the process is done forcefully using kill -9.
Suggestion is to do a graceful shutdown with retries and do a force kill only if graceful shutdown is not successful.
Stop section from ranger-tagsync-services.sh and ranger-tusersync-services.sh
lif [ "${action}" == "STOP" ]; then
WAIT_TIME_FOR_SHUTDOWN=2
NR_ITER_FOR_SHUTDOWN_CHECK=15
if [ -f "$pidf" ] ; then
pid=`cat $pidf` > /dev/null 2>&1
echo "Found Apache Ranger TagSync Service with pid $pid, Stopping..."
kill -9 $pid > /dev/null 2>&1
sleep 1 #Give kill -9 sometime to "kill"
if ps -p $pid > /dev/null; then
echo "Wow, even kill -9 failed, giving up! Sorry.."
else
rm -f $pidf
echo "Apache Ranger Tagsync Service pid = ${pid} has been stopped."
fi
else
echo "Ranger Tagsync Service not running"
fi
exit;
