sandflee created YARN-3387:
------------------------------

             Summary: container complete message couldn't pass to am if am restarted and rm
changed
                 Key: YARN-3387
                 URL: https://issues.apache.org/jira/browse/YARN-3387
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.6.0
            Reporter: sandflee


suppose am work preserving and rm ha is enabled.
container complete message is passed to appattemt.justFinishedContainers in rm。in normal
situation,all attempt in one app shares the same justFinishedContainers, but when rm changed,
every attempt has it's own justFinishedContainers, so in situations below, container complete
message couldn't passed to am:
1, am restart
2, rm changes
3, container launched by first am completes
container complete message will be passed to appAttempt1 not appAttempt2, but am pull finished
containers from appAttempt2 (currentAppAttempt)
