Doris Gu updated HDFS-11753:
----------------------------
Description:
1.Add support -h. Right now, if I use *hdfs journalnode -h* , I straightly
start journalnode daemon. But generally speaking， I just want to look at the
usage.
2.Add exception catch and termination. If I start journalnode with different
directions stored pids, I get servel journalnode daemons that don't work for I
config the same port.
