Craig Condit updated YUNIKORN-2840:
-----------------------------------
Target Version: 1.8.0 (was: 1.7.0)
> sortQueues: fair max performance and correctness change
> -------------------------------------------------------
>
> Key: YUNIKORN-2840
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2840
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler
> Reporter: Wilfred Spiegelenburg
> Assignee: Tzu-Hua Lan
> Priority: Major
>
> In YUNIKORN-2678 the fair queue sorting was improved to take guaranteed quota
> into account correctly. During the review there were two minor points left
> over that would need improving:
> * performance
> * correctness on change
> Currently {{GetFairMaxResource()}} gets called for each child this does a
> recursive call back up the queue hierarchy. This is a performance loss
> specially when sorting a deep hierarchy or a larger number of children.
> The parent details for a real fair comparison between the children should
> also not change. When they do, as in the current implementation, two children
> might use different inputs when sorted.
