[jira] [Created] (YARN-2413) capacity scheduler will overallocate vcores

Allen Wittenauer created YARN-2413:
--------------------------------------

             Summary: capacity scheduler will overallocate vcores
                 Key: YARN-2413
                 URL: https://issues.apache.org/jira/browse/YARN-2413
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
    Affects Versions: 2.2.0, 3.0.0
            Reporter: Allen Wittenauer
            Priority: Critical


It doesn't appear that the capacity scheduler is properly allocation vcores when making scheduling decisions, which results in overallocation of CPU resources.
