# org.opentest4j.AssertionFailedError: expected: <2> but was: <3>
([Report|https://ge.apache.org/s/ndoj6s2stb446/tests/task/:core:test/details/kafka.api.PlaintextAdminIntegrationTest/testConsumerGroupsDeprecatedConsumerGroupState(String%2C%20String)%5B1%5D?expanded-stacktrace=WyIxIl0&top-execution=2])

The flaky can't be reproduce in my local, but can be simulated with the
attached patch. (Uncomment the sleep 1 sec)
The root cause is that the member rejoining group after it was removed from
group. Same issue occur on KAFKA-18297 too.
