---------------------------------------
Summary: 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
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.
