Zian Chen commented on YARN-8016:

Hi [~yufeigu] , thank you for your suggestions. As Wangda give the comments regarding FairScheduler
part, I'll focus on CS part first. We could discuss further if the situation changes. Meanwhile,
I will update the patch according to Wangda's comments. Please let me know if you have any
other comments or suggestions. Thanks!

> After YARN-3635/YARN-6689, PlacementRule becomes a common interface which can be used
by scheduler and can be dynamically updated by scheduler according to configs. There're some
other works.

> - No example of PlacementRule except the user-group mapping one.
> This JIRA is targeted to refine PlacementRule interfaces and add another PlacementRule
