Hi @lianetm, I have enabled the However, I believe this is a separate issue that needs investigation and is not related to this patch. |

Thanks for the patch @frankvicky! Could you enable here all the tests that pass so we can have validation of the change? We can investigate a bit the one that still fails, if it's related to another issue we can track and address it separately. Makes sense? |

Hi @lianetm
I have found that the cause of testConsumerWithAuthenticationFailure failing is due to a non-retriable assertion.
If we pass the assertion as an argument to verifyWithRetry, it will fail because we don't catch AssertionFailedError (and we shouldn't do it). The subscribe call needs to wait for metadata updates and it's not as quick as assign, so there's a high chance it will fail on the first poll. As mentioned, when we pass the assertion as an argument, it will fail with AssertionFailedError and cannot retry.

interesting, makes sense to me.
But then, couldn't we just change the
verifyWithRetry(assertEquals(1, consumer.poll(Duration.ofMillis(1000)).count))
to
verifyWithRetry(consumer.poll(Duration.ofMillis(1000)).count == 1)
(just to avoid introducing this new verifyWithRetryPredicate)

Sure, i'll give it a try

Looks like it does not use a consumer. Could you double check and if so, then no need to run it for both consumers.

similar as above, looks like it does need to run for both consumers?

In short, the new async consumer's topic metadata operations are unwared of metadata errors because of not overriding
requireSubscriptionMetadata.For further details, please refer to the jira ticket.
