Mason Chen updated FLINK-30833:
-------------------------------
Description: For testing purposes, closing a metric group is required to
verify logic that maintains metrics. The TestMetricGroup needs to extend
AbstractMetricGroup<> to support this. (was: The internal
TestingMetricRegistry does not register an action when a metric group is
closed. This would allow the use of the MetricListener to test logic that
closes metric groups.
[https://github.com/apache/flink/blob/44dbb8ec84792540095b826616d0f21b745aa995/flink-test-utils-parent/flink-test-utils/src/main/java/org/apache/flink/metrics/testutils/MetricListener.java#L53]
This change doesn't require exposing any public API and is transparent.)
