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

             Summary: FSAppAttempt adds duplicate ResourceRequest to demand in updateDemand.
                 Key: YARN-4979
                 URL: https://issues.apache.org/jira/browse/YARN-4979
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.7.2, 2.8.0
            Reporter: zhihai xu
            Assignee: zhihai xu


FSAppAttempt adds duplicate ResourceRequest to demand in updateDemand. We should only count ResourceRequest for ResourceRequest.ANY when calculate demand.
Because {{hasContainerForNode}} will return false if no container request for ResourceRequest.ANY and both {{allocateNodeLocal}} and {{allocateRackLocal}} will also decrease the number of containers for ResourceRequest.ANY.
This issue may cause current memory demand overflow(integer) because duplicate requests can be on multiple nodes.
