> The RM should expose the name of the ResourceCalculator being used when AMs 
> register, as part of the RegisterApplicationMasterResponse.
> This will allow applications to make better decisions when scheduling. 
> MapReduce for example, only looks at memory when deciding it's scheduling, 
> even though the RM could potentially be using the DominantResourceCalculator.
