stack resolved HBASE-503.
-------------------------
Resolution: Won't Fix
Issue is too old and original description was about a process watched by errant
babysitter.
> cluster won't shut down
> -----------------------
>
> Key: HBASE-503
> URL: https://issues.apache.org/jira/browse/HBASE-503
> Project: Hadoop HBase
> Issue Type: Bug
> Affects Versions: 0.16.0, 0.1.0, 0.2.0
> Reporter: stack
> Priority: Minor
>
> Master is stuck trying to shutdown. It gets confused if its not running the
> shutdown. Scenario is cluster is being monitored by a watcher process. When
> a server goes down, its restarted. In this environment, all hbase was
> updated then each server was restarted. The regionservers bounced fine but
> the master won't go down. Its stuck servicing reports of newly started
> regionservers to whom it sends a shutdown.... but cluster is of such a size
> that the master hasn't gone down by the time the regionserver starts again.
> Here is how the master log looks for one server:
