-----------------------------------
Summary: RM should expose the name of the ResourceCalculator being
used when AMs register
Key: YARN-2448
URL: https://issues.apache.org/jira/browse/YARN-2448
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Varun Vasudev
Assignee: Varun Vasudev
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.
