> Reporter: Wilfred Spiegelenburg

> The PlacementRule interface was introduced to be used by all schedulers as per YARN-3635. The CapacityScheduler is using it but the FairScheduler is not and is using its own rule definition.
> YARN-8948 cleans up the implementation and removes the CS references which should allow this change to go through.
> This would be the first step in using one placement rule engine for both schedulers.
