             Summary: YarnResourceManagerDriver.getPendingRequestsAndCheckConsistency only returns container requests for first matching equivalent resource
                 Key: FLINK-19556
                 URL: https://issues.apache.org/jira/browse/FLINK-19556
             Project: Flink
          Issue Type: Task
          Components: Deployment / YARN
    Affects Versions: 1.12.0
            Reporter: Till Rohrmann
             Fix For: 1.12.0


The {{YarnResourceManagerDriver}} will retrieve the number of pending container requests for a given {{Resource}} by calling {{YarnResourceManagerDriver.getPendingRequestsAndCheckConsistency(Resource)}}. Part of this method is to find the equivalent resources for the given resource. Next we find for every equivalent resource the matching container requests. Instead of unifying these collection of container requests, the method returns the first non-empty collection. This might return an incomplete set of container requests if the Yarn respects the vcores of resources given to {{AMRMClientAsync.getMatchingRequests}}.
