[jira] [Created] (YUNIKORN-1468) Remove completed apps from queue object

Wilfred Spiegelenburg created YUNIKORN-1468:
-----------------------------------------------

             Summary: Remove completed apps from queue object
                 Key: YUNIKORN-1468
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1468
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: core - scheduler
            Reporter: Wilfred Spiegelenburg


Completed applications remain linked to a queue and never cleaned up. This is a similar problem as we have seen in YUNIKORN-1440.

The problem is however larger than just keeping it linked and not cleaning up:
 * the completedApplications map in the queue is not safe for appID reuse as the map key is the application ID without suffix.
 * a dynamic queue is removed when empty: a newly created queue with the same path does not have any history which is incorrect
 * the completedApplications map in the queue is never cleaned up
