             Summary: MiniYARNCluster's start() may return before configuration 
is updated
                 Key: YARN-2642
             Project: Hadoop YARN
          Issue Type: Bug
          Components: test
            Reporter: Marcelo Vanzin

When starting a new MiniYARNCluster, it's possible that the start() method 
returns before the configuration has been updated by ClientRMService. If that 
YarnConfiguration.RM_ADDRESS will contain the wrong RM address (generally with 
port 0), and that can cause tests to fail.
