             Summary: Corrupted state from a previous version can still cause RM to fail with
NPE on FairScheduler
                 Key: YARN-9198
                 URL: https://issues.apache.org/jira/browse/YARN-9198
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler, resourcemanager
    Affects Versions: 2.8.5, 3.1.0

Previously, RM may fail with NPE due to YARN-4347,YARN-4000. After these fixes, FairScheduler
still has the same potential issue.
