I think its better to change to rmcontext so that other schedulers will be able

> 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.
> - There's no way to initialize PlacementRule.
> - No example of PlacementRule except the user-group mapping one.
> This JIRA is targeted to refine PlacementRule interfaces and add another
> PlacementRule example.
