Daniel Templeton commented on YARN-6953:
----------------------------------------

+1 from me as well, except that the patch doesn't appear to apply anymore.

> Clean up ResourceUtils.setMinimumAllocationForMandatoryResources() and 
> setMaximumAllocationForMandatoryResources()

> The {{setMinimumAllocationForMandatoryResources()}} and 
> {{setMaximumAllocationForMandatoryResources()}} methods are quite convoluted. 
>  They'd be much simpler if they just handled CPU and memory manually instead 
> of trying to be clever about doing it in a loop.  There are also issues, such 
> as the log warning always talking about memory or the last element of the 
> inner array being a copy of the first element.
