> 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
> Priority: Major
>
> 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.
