    Description

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

      2013-03-28 19:21:06,243 [main] INFO org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl: Security enabled - updating secret keys now
      2013-03-28 19:21:06,243 [main] INFO org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl: Registered with ResourceManager as RM:PORT with total resource of <me
      mory:12288, vCores:16>
      2013-03-28 19:21:06,244 [main] INFO org.apache.hadoop.yarn.service.AbstractService: Service:org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl is started.
      2013-03-28 19:21:06,245 [main] INFO org.apache.hadoop.yarn.service.AbstractService: Service:org.apache.hadoop.yarn.server.nodemanager.NodeManager is started.
      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.
