Date Tue, 31 Oct 2017 18:15:00 GMT
Haibo Chen created YARN-7421:
--------------------------------

             Summary: Preserve execution type for containers to be promoted by AM post YARN-1015
                 Key: YARN-7421
                 URL: https://issues.apache.org/jira/browse/YARN-7421
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: YARN-1011
            Reporter: Haibo Chen
            Assignee: Haibo Chen


>From offline discussion with [~asuresh], if an AM tries to promote or increase a container
whose enforceExecutionType is set to false, the scheduler may, in the presence of oversubscription,
 allocate an OPPORTUNISTIC container. This should not happen given the contract we have in
container update API.
