----------------------------------

             Summary: YARN deployment hangs when requested container is above the maximum vcore size
                 Key: FLINK-13685
                 URL: https://issues.apache.org/jira/browse/FLINK-13685
             Project: Flink
          Issue Type: New Feature
          Components: Deployment / YARN
    Affects Versions: 1.8.1
            Reporter: Gyula Fora


When deploying on YARN flink explicitly checks whether the requested container memory is smaller than yarn.nodemanager.resource.cpu-vcores.

Unfortunately this doesn't guarantee that the request can be fulfilled if yarn.scheduler.maximum-allocation-vcores is set to a lower number.

In these cases flink will just keep trying to request a container but will never succeed.
