[jira] [Created] (YARN-8191) Fair scheduler: queue deletion without RM restart

Gergo Repas created YARN-8191:
---------------------------------

             Summary: Fair scheduler: queue deletion without RM restart
                 Key: YARN-8191
                 URL: https://issues.apache.org/jira/browse/YARN-8191
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler
    Affects Versions: 3.0.1
            Reporter: Gergo Repas
            Assignee: Gergo Repas


The Fair Scheduler never cleans up queues even if they are deleted in the allocation file, or were dynamically created and are never going to be used again. Queues always remain in memory which leads to two following issues.
 # Steady fairshares aren’t calculated correctly due to remaining queues
 # WebUI shows deleted queues, which is confusing for users (YARN-4022).

We want to support proper queue deletion without restarting the Resource Manager:
 # Static queues without any entries that are removed from fair-scheduler.xml should be deleted from memory.
 # Dynamic queues without any entries should be deleted.
 # RM Web UI should only show the queues defined in the scheduler at that point in time.
