------------------------------------

             Summary: Scheduler recovery failure occasionally while recovering a large number of applications
                 Key: YUNIKORN-549
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-549
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: shim - kubernetes
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang


Current recovery logic adds application back to based on the pods reported by the informers/listers. In some conditions, the recovery of an app could fail if the app has both Running and Pending pods. This is because the shim marks an app with a Recovery if the informer notified the scheduler before the lister function gets called. The is not working as expected consistently, we need a stable implementation in order to tell if an app needs recovery or not.
