Wangda Tan created YARN-1449:
--------------------------------

             Summary: Protocol changes in NM side to support change container resource
                 Key: YARN-1449
                 URL: https://issues.apache.org/jira/browse/YARN-1449
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
    Affects Versions: 2.2.0
            Reporter: Wangda Tan
            Assignee: Wangda Tan


As described in YARN-1197, we need add API in NM to support
1) Add a "changeContainersResources" method in ContainerManagementProtocol
2) Can get succeed/failed increased/decreased containers in response of "changeContainersResources"
3) Add a "new decreased containers" field in NodeStatus which can help NM notify RM such changes
