                 Key: YARN-5241
                 URL: https://issues.apache.org/jira/browse/YARN-5241
             Project: Hadoop YARN
          Issue Type: Bug

    Affects Versions: 2.7.2, 2.6.1, 2.5.0, 2.8.0
            Reporter: ChenFolin


NodeManager heartbeat event NODE_UPDATE and ApplicationMaster allocate operate may cause repeat container completed, it can lead something wrong.

Node releaseContainer can pervent repeat release operate:
like:
public synchronized void releaseContainer(Container container) {
    if (!isValidContainer(container.getId())) {
      LOG.error("Invalid container released " + container);
      return;
    }

FSAppAttempt containerCompleted did not prevent repeat container completed operate.

Detail logs at attach file.
