> 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.
