Varun Vasudev updated YARN-2448:
--------------------------------
Attachment: apache-yarn-2448.2.patch
Uploaded a new patch to address the concerns raised by Karthik, Sandy and
Vinod. Instead of exposing the resource calculator, expose the resources used
by the scheduler instead.
> RM should expose the name of the ResourceCalculator being used when AMs
> register

> 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.
