> 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.
