[jira] [Comment Edited] (YUNIKORN-560) Yunikorn recovery deletes
existing placeholders
[ https://issues.apache.org/jira/browse/YUNIKORN-560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17300205#comment-17300205 ]

------------------------------------------------------------------
One of the approaches being considered is to use owner reference to fix the issue, but we cannot use the owner reference cross namespace, so we need to find some other solution.
Since the fix is not as straight forward as just set some owner reference, and we need to discuss the possible solutions I would move this out from the scope or 0.10 release.
