> Key: HBASE-4951
> 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: 0.92.0, 0.90.5
>
>
> 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.
