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

             Summary: ExecutionGraph metrics collide on restart
                 Key: FLINK-21510
                 URL: https://issues.apache.org/jira/browse/FLINK-21510
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: Chesnay Schepler
             Fix For: 1.13.0


The ExecutionGraphBuilder registers several metrics directly on the JobManagerJobMetricGroup, which are never cleaned up.

When the AdaptiveScheduler re-creates the EG these will collide with metrics of prior attempts.
