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

             Summary: MetricQueryService actor name collision
                 Key: FLINK-4784
                 URL: https://issues.apache.org/jira/browse/FLINK-4784
             Project: Flink
          Issue Type: Bug
          Components: Metrics
    Affects Versions: 1.1.2
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.2.0


The name of the MetricQueryService actor is currently fixed, which can lead to collisions if multiple TaskManagers run in the same actor system, as is the case for the MiniCluster.

We can append the TaskManager ResourceID to make the name unique for every TaskManager. The MetricFetcher would still be able to reliable infer the correct actor name.
