------------------------------------
Summary: MiniYARNCluster's start() may return before configuration
is updated
Key: YARN-2642
URL: https://issues.apache.org/jira/browse/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
happens,
YarnConfiguration.RM_ADDRESS will contain the wrong RM address (generally with
port 0), and that can cause tests to fail.
