> 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.
