Description

Somtime, Using 'kylin.sh stop' can't kill kylin process,it's better to use 'kill -9' to kill process.
It will cause 'port is used' error when start kylin, and error messages like this"

Which error is kylin.sh script,
if [ -f "${KYLIN_PID}" ]
then
PID=`cat $KYLIN_PID`
if ps -p $PID > /dev/null
then
echo "stopping Kylin:$PID"
kill $PID – sometime, this action couldn't kill process
rm ${KYLIN_PID}
exit 0
It is should use 'kill -9 $PID' to instead 'kill $PID'.
