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"

      四月 27, 2017 2:56:16 下午 org.apache.coyote.AbstractProtocol init
      严重: Failed to initialize end point associated with ProtocolHandler ["http-bio-7070"]

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'.
