-----------------------------------------------
@Xufeng
Yes you are right.. the patch address only one problem where the master alone
is started.
We can check for the shutdown node while waiting for Root and if the shut down
node does not exist we can come out of wait.
Thanks for the finding.
> master process can not be stopped when it is initializing

> It is easy to reproduce by following step:
> step1:start master process.(do not start regionserver process in the cluster).
> the master will wait the regionserver to check in:
> org.apache.hadoop.hbase.master.ServerManager: Waiting on regionserver(s) to
> checkin
> step2:stop the master by sh command bin/hbase master stop
> result:the master process will never die because catalogTracker.waitForRoot()
> method will block unitl the root region assigned.
