tries to recover completed apps and schedules placeholder pods.
Ayub Pathan created YUNIKORN-575:
------------------------------------
Summary: Regression: Post restart, Yunikorn tries to recover completed apps and schedules placeholder pods.
Key: YUNIKORN-575
URL: https://issues.apache.org/jira/browse/YUNIKORN-575
Project: Apache YuniKorn
Issue Type: Bug
Components: shim - kubernetes
Reporter: Ayub Pathan
Attachments: Screen Shot 2021-03-15 at 9.27.10 PM.png, yk_recover.log
* Post restart, YK tries to recover the completed apps and schedules placeholder pods(even though the real pods are in completed state), which may not be needed. This leads to resource mismanagement.

* *All the completed apps are marked as failed, post restart and the allocations are not released. This could be a resource leak post restart.*
