Daniel Templeton commented on YARN-7123:
----------------------------------------
Per offline discussion with [~kasha], it really is an issue, and we don't need
it to be configurable. Let's just make the default be a
{{DominantResourceCalculator}} instance.
> FairScheduler.getResourceCalculator() returns an instance of
> DefaultResourceCalculator regardless of the configuration
