---------------------------------------
Summary: Retrospect update ApplicationPriority response API
Key: YARN-4164
URL: https://issues.apache.org/jira/browse/YARN-4164
Project: Hadoop YARN
Issue Type: Sub-task
Components: resourcemanager
Reporter: Rohith Sharma K S
Currently {{ApplicationClientProtocol#updateApplicationPriority()}} API returns
empty UpdateApplicationPriorityResponse response.
But RM update priority to the cluster.max-priority if the given priority is
greater than cluster.max-priority. In this scenarios, need to intimate back to
client that updated priority rather just keeping quite where client assumes
that given priority itself is taken.
During application submission also has same scenario can happen, but I feel
when
explicitly invoke via ApplicationClientProtocol#updateApplicationPriority(),
response should have updated priority in response.
