             Summary: Implement the core QUEUE_LENGTH_THEN_RESOURCES OContainer allocation policy
                 Key: YARN-11005
                 URL: https://issues.apache.org/jira/browse/YARN-11005
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Andrew Chung


This sub-task contains the bulk of the work that will implement the new resource-aware Opportunistic container allocation policy {{QUEUE_LENGTH_THEN_RESOURCES}}.
The core tasks here are to:
1. Allow {{ClusterNode}} to be allocated resource-aware using information from {{RMNode}},
2. Add the {{QUEUE_LENGTH_THEN_RESOURCES}} {{LoadComparator}}, and 
3. Implement the new sorting logic and the logic to determine whether a node can queue Opportunistic containers in case the {{QUEUE_LENGTH_THEN_RESOURCES}} policy is chosen.
