> The HRegionServer calls HBaseServer:
> {code}
> public void start() {
> startThreads();
> openServer();
> }
> {code}
> but the server can start accepting RPCs once the threads have been started,
> but if they do, they throw ServerNotRunningException until openServer runs.
> We should probably
> 1) Catch the remote exception and retry on the master
> 2) Look into whether the start() behavior of HBaseServer makes any sense.
> Why would you start accepting RPCs only to throw back
> ServerNotRunningException?
