> In a HA cluster, region server got stuck in reportForDuty retry loop if the active master
is restarting and later on master switch happens before it reports successfully.
> Root cause is same as HBASE-13317, but the region server tried to connect master when
it was starting, so rssStub reset didnt happen as
> {code}
>   if (ioe instanceof ServerNotRunningYetException) {
> 	LOG.debug("Master is not running yet");
>   }
> {code}
> When master starts, master switch happened. So RS always tried to connect to standby
master.
