Daniel Templeton commented on YARN-6610:
----------------------------------------
After a long discussion with [~kasha], I think I'm now convinced that there's
no correctness issue with using DRF in a multi-resource configuration. There
is, of course, the performance issue created by increasing the number of
dimensions in the resource comparisons, but that's an issue to be resolved for
resource types in general. I think the posted patch should be fine.
> DominantResourceCalculator.getResourceAsValue() dominant param is no longer
> appropriate

> The {{dominant}} param assumes there are only two resources, i.e. true means
> to compare the dominant, and false means to compare the subordinate. Now
> that there are _n_ resources, this parameter no longer makes sense.
