-------------------------------------

             Summary: ResourceManager NPE during allocateNodeLocal
                 Key: YARN-351
                 URL: https://issues.apache.org/jira/browse/YARN-351
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.0.2-alpha
            Reporter: Lohit Vijayarenu
            Priority: Critical


ResourceManager seem to die due to NPE shown below on FairScheduler.
This is easily reproduced on a cluster with multiple racks and nodes within each rack. Simple job with multiple tasks on each node triggers NPE in RM.

Without understanding actual workings, I tried to do a null check which looked like it solved problem. But I am not sure if that is the right behavior yet.

I feel this is serious enough to be marked as blocker, what do you guys think?
