zentol opened a new pull request #15975: URL: https://github.com/apache/flink/pull/15975
Modified version of #15904. Slotmanagers register metrics in start(), but only unregister them in close(). This has 2 issues: a) If the SM is restarted it cannot re-register the metrics because the old ones are still present; this isn't a critical problem (because the old ones still work) but it produces unnecessary logging noise b) The metric may produce an NPE when accessed by a reporter during suspend(). -- This is an automated message from the Apache Git Service.
