             Summary: YARN CapacityScheduler QueueMetrics has missing metrics for parent queues having same name
                 Key: YARN-9766
                 URL: https://issues.apache.org/jira/browse/YARN-9766
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Tarun Parimi
            Assignee: Tarun Parimi


In Capacity Scheduler, we enforce Leaf Queues to have unique names. But it is not the case for Parent Queues. For example, we can have the below queue hierarchy, where "b" is the queue name for two different queue paths root.a.b and root.a.d.b . Since it is not a leaf queue this configuration works and apps run fine in the leaf queues 'c'  and 'e'.
 * root
 ** a
 *** b
 **** c
 *** d
 **** b
 ***** e

But the jmx metrics does not show the metrics for the parent queue "root.a.d.b" . We can see metrics only for "root.a.b" queue.
