------------------------------

SUCCESS: Integrated in Hadoop-Hdfs-trunk #1868 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1868/])
YARN-2448. Changed ApplicationMasterProtocol to expose RM-recognized resource types to the
AMs. Contributed by Varun Vasudev. (vinodkv: rev b67d5ba7842cc10695d987f217027848a5a8c3d8)

> 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.
