---------------------------

             Summary:  Yarn can't submit application, resourcemanager get stuck but not dead
                 Key: YARN-10700
                 URL: https://issues.apache.org/jira/browse/YARN-10700
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 3.2.1
            Reporter: leix
         Attachments: logs.png, logs_1.png, logs_2.png

We hava a hadoop3.2.1 cluster which resoucemanager stuck several times within few weeks,
yet resoucemanager is not dead. it seems something blocks threads in resourcemanager waiting
for lock. 
According to our jstack and rm log , it looks AsyncDispatcher was stuck. We disable printEventQueueDetails
solved this problem. 
It should be a bug and need to be fixed.
