Arun C Murthy commented on YARN-893:
------------------------------------
[~kj-ki] & [~ozawa] - the {{DefaultResourceCalculator}} is meant to not use
vcores by design - if vcores is desired, one should use the
{{DominantResourceCalculator}}. Makes sense?
> Capacity scheduler allocates vcores to containers but does not report it in
> headroom
