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

             Summary: AbstractCoordinator.testWakeupAfterSyncGroupReceivedExternalCompletion seems flaky
                 Key: KAFKA-15474
                 URL: https://issues.apache.org/jira/browse/KAFKA-15474
             Project: Kafka
          Issue Type: Test
    Affects Versions: 3.6.0
            Reporter: Philip Nee


Ran into test failures when running the full AbstractCoordinatorTest unit test suit.

It is not very easy to reproduce, I seem to need to run the full unit module to "sometimes" reproduce it.
