----------------------------------
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.
