Wilfred Spiegelenburg commented on YUNIKORN-982:
------------------------------------------------
PR opened that handles the three cases correctly without causing internal stats
to go out of sync:
* placeholder is same as real (expected and already working case)
* placeholder is smaller than real (remove placeholders)
* placeholder is larger than real (adjust usage in queue and nodes)
> Handle placeholders that are different from real allocations

> Key: YUNIKORN-982
> URL: https://issues.apache.org/jira/browse/YUNIKORN-982
> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - scheduler
> Affects Versions: 0.12
> Reporter: Wilfred Spiegelenburg
> Assignee: Wilfred Spiegelenburg
> Priority: Major
> Labels: pull-request-available
>
> If a placeholder is not the same resource size as the real allocation that
> replaces it YuniKorn will leak resources. In YUNIKORN-580 a log entry was
> added to detect the case. It will still cause the out of sync state but we
> can detect it.
> Handling the issue in the code outright is a better solution.
