Daniel Templeton commented on YARN-6610:
----------------------------------------
[~yufeigu], yeah, you're right about unit tests. There is currently the
{{TestResourceCalculator}} class, but it only tests {{compare()}} when the
cluster resource is 0, and it does nothing to test more than 2 resources.
> 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.
