             Summary: Add total cluster capacity to AllocateResponse
                 Key: YARN-2463
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Varun Vasudev
            Assignee: Varun Vasudev

YARN-2448 exposes the ResourceCalculator being used by the scheduler so that 
AMs can make better decisions when scheduling tasks. The 
DominantResourceCalculator needs the total cluster capacity to function 
correctly. We should add this information to the AllocateResponse.
