> TaskManager metrics are registered twice
> ----------------------------------------
>
> Key: FLINK-7100
> URL: https://issues.apache.org/jira/browse/FLINK-7100
> Project: Flink
> Issue Type: Bug
> Components: Local Runtime, Metrics
> Affects Versions: 1.3.0, 1.4.0
> Reporter: Chesnay Schepler
> Assignee: Fang Yong
> Labels: flip-6
> Fix For: 1.4.0, 1.3.2
>
>
> TaskManager metrics are currently registered twice, once when the TaskManager
> is started and once when the TaskManager associates with a JobManager.
> Originally the metrics were registered when the TM associates with the JM and
> unregistered upon disassociation.
> 9e9776f17ed18b12af177e31ab0bc266236f85ef modified the {{TaskManager}} to use
> the {{TaskManagerServices}}, which when loaded _also_ register the metrics.
> I suggest to remove the registrations that happen upon (dis-)association.
