zhuqi created YARN-8995:
---------------------------

             Summary: Log the event type of the too big event queue size, and add the information to the metrics. 
                 Key: YARN-8995
                 URL: https://issues.apache.org/jira/browse/YARN-8995
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: metrics, nodemanager, resourcemanager
    Affects Versions: 3.1.0
            Reporter: zhuqi
            Assignee: zhuqi


In our growing cluster，there are unexpected situations that cause some event queues to block the performance of the cluster, such as the bug of  https://issues.apache.org/jira/browse/YARN-5262 . I think it's necessary to log the event type of the too big event queue size, and add the information to the metrics, and the  threshold of queue size is a parametor which can be changed.
