             Summary: Skip dispatching opportunistic containers to nodes whose queue is already full
                 Key: YARN-7587
                 URL: https://issues.apache.org/jira/browse/YARN-7587
             Project: Hadoop YARN
          Issue Type: Sub-task
    Affects Versions: 2.9.0
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang


When there is a lot of opportunistic container requests, even if NM queue is full, RM continues to dispatch O containers to that node. Such allocations will be killed immediately by NM causing a waste of resource. Propose to exclude such nodes in the load monitor.
