### Description of PR YARN-11211 broke the JMX QueueMetrics, detailed root cause analysis in the [Jira](https://issues.apache.org/jira/browse/YARN-11490?focusedCommentId=17721370&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17721370). ### How was this patch tested? ```shell # run a long sleep job hadoop-3.4.0-SNAPSHOT/bin/yarn jar hadoop-3.4.0-SNAPSHOT/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-3.4.0-SNAPSHOT-tests.jar sleep -m 1 -r 1 -rt 1200000 -mt 20 # tried to validate an add-queue operation curl -X POST -H 'Content-Type: application/xml' -d @addqueue.xml localhost:8088/ws/v1/cluster/scheduler-conf/validate # verified that no root.a is in the jmx response curl http://localhost:8088/jmx | jq # validated a queue config change curl -X POST -H 'Content-Type: application/json' -d @defaultqueue.json localhost:8088/ws/v1/cluster/scheduler-conf/validate # submitted other jobs # repeated these steps multiple times and verified that the jmx endpoint still shows valid data (e.g.: appsRunning/appsPending works, there is no root.a in the response) # created the root.a queue curl -X PUT -H 'Content-Type: application/xml' -d @removequeue.xml localhost:8088/ws/v1/cluster/scheduler-conf # verified that the jmx response contains the root.a (2x times: "QueueMetrics,q0=root,q1=a" and "PartitionQueueMetrics,partition=,q0=root,q1=a") curl http://localhost:8088/jmx | jq ``` ```shell # restarted yarn, then I created the root.a queue, and compared the jmx response to the previous test curl -X PUT -H 'Content-Type: application/xml' -d @removequeue.xml localhost:8088/ws/v1/cluster/scheduler-conf curl http://localhost:8088/jmx | jq ``` Note: based on my understanding of the code `PartitionQueueMetrics` can't show the appsRunning/appsPending (at least not for the CapacityScheduler). ### For code changes: - [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
