             Summary: AMRMProxyPolicies should accept heartbeat response from new/unknown subclusters
                 Key: YARN-8481
                 URL: https://issues.apache.org/jira/browse/YARN-8481
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Botong Huang
            Assignee: Botong Huang


Currently BroadcastAMRMProxyPolicy assumes that we only span the application to the sub-clusters instructed by itself via _splitResourceRequests_. However, with AMRMProxy HA, second attempts of the application might come up with multiple sub-clusters initially without consulting the AMRMProxyPolicy at all. This leads to exceptions in _notifyOfResponse._ It should simply allow the new/unknown sub-cluster heartbeat responses.
