Date Thu, 28 Mar 2013 19:49:17 GMT
Robert Joseph Evans created YARN-515:
----------------------------------------

             Summary: Node Manager not getting the master key
                 Key: YARN-515
                 URL: https://issues.apache.org/jira/browse/YARN-515
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.0.4-alpha
            Reporter: Robert Joseph Evans
            Priority: Blocker


On branch-2 the latest version I see the following on a secure cluster.

2013-03-28 19:21:07,257 [Node Status Updater] ERROR org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl:
Caught exception in status-updater
java.lang.NullPointerException
        at org.apache.hadoop.yarn.server.security.BaseContainerTokenSecretManager.getCurrentKey(BaseContainerTokenSecretManager.java:121)
        at org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl$1.run(NodeStatusUpdaterImpl.java:407)

The Null pointer exception just keeps repeating and all of the nodes end up being lost.  It
looks like it never gets the secret key when it registers.
