Daniel Templeton commented on YARN-6057:
----------------------------------------
In the case of both minimum and maximum, resource requests that are out of
bounds are quietly adjusted to be in bounds. (See
{{DefaultResourceCalculator.normalize()}} and
{{DominantResourceCalculator.normalize()}}) The minimum will also prevent NMs
that have fewer vcores from starting. (See
{{ResourceTrackerService.registerNodeManager()}}.)
