>                 URL: https://issues.apache.org/jira/browse/HBASE-4951
>             Project: HBase
>          Issue Type: Bug
>          Components: master
>    Affects Versions: 0.90.3
>            Reporter: xufeng
>            Assignee: ramkrishna.s.vasudevan
>            Priority: Critical
>             Fix For: 0.90.6
>         Attachments: HBASE-4951.patch
> 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.
