Description

When addressing HBASE-13011, TestHMasterRPCException failed twice in PreCommit Build.

I found that the test itself has a problem. We start a HMaster, and then we continue calling isMasterRunning and expected a ServerNotRunningYetException.

But it is possible that when we connect to HMaster, it has already finished initialization, and we just get a 'true' response instead of an Exception.(Just add a 'Thread.sleep(1000);' after 'HMaster hm = new HMaster(conf, cp);', you can get a stable failure).
