[jira] [Created] (YUNIKORN-676) App pending in one queue seems to block app scheduling on the other queue

Weiwei Yang created YUNIKORN-676:
------------------------------------

             Summary: App pending in one queue seems to block app scheduling on the other queue
                 Key: YUNIKORN-676
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-676
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: core - scheduler, shim - kubernetes
            Reporter: Weiwei Yang
             Fix For: 0.11


[~yuchaoran2011] found this issue on their cluster. 
It looks like when we have 2 queues, root.a and root.b, if we submit an app with invalid node constraints (e.g node affinity to some non-exist node) to root.a, the app will be pending (expected); however, in some cases, apps in root.b are blocked. Restarting the scheduler seems to be able to solve this. Root cause unclear yet, reproduction steps unclear as well at the moment.
