Liang Lee commented on HBASE-5844:
----------------------------------
And I still have another question:in the hbase-daemon.sh file,in the
cleanZNode() funtion ,which znode is deleted ?
Under the normal scenario,when RegionServer starts ,it will create temporary
znode on Zookeeper in the path /habse/rs,and what we delete in the cleanZNode()
funtion ?
Thank you!

> today, if the regions server crashes, its znode is not deleted in ZooKeeper.
> So the recovery process will stop only after a timeout, usually 30s.
> By deleting the znode in start script, we remove this delay and the recovery
> starts immediately.
