Haibo Chen created YARN-6921:
--------------------------------

             Summary: Allow resource request to opt out of oversubscription
                 Key: YARN-6921
                 URL: https://issues.apache.org/jira/browse/YARN-6921
             Project: Hadoop YARN
          Issue Type: Task
          Components: scheduler
    Affects Versions: 3.0.0-alpha3
            Reporter: Haibo Chen
            Assignee: Haibo Chen


Guaranteed container requests, enforce tag true or not, are by default eligible for oversubscription, and thus can get OPPORTUNISTIC container allocations. We should allow them to opt out if their enforce tag is set to true.
