…ting topics (apache#14695) TestUtils.createTopicWithAdmin calls waitForAllPartitionsMetadata which waits for partition(s) to be present in each brokers' metadata cache. This is a sufficient check in ZK mode because the controller sends an LISR request before sending an UpdateMetadataRequest which means that the partition in the ReplicaManager will be updated before the metadata cache. In KRaft mode, the metadata cache is updated first, so the check may return before partitions and other metadata listeners are fully initialized. Testing: Insert a Thread.sleep(100) in BrokerMetadataPublisher.onMetadataUpdate after // Publish the new metadata image to the metadata cache. metadataCache.setImage(newImage) and run EdgeCaseRequestTest.testProduceRequestWithNullClientId and the test will fail locally nearly deterministically. After the change(s), the test no longer fails.

@divijvaidya This one was missing the change in some test files, so we should probably review TopicCommandIntegrationTest. I suspect 3.5 will have more conflicts. |

I removed the file that didn't exist and added the controllerServer arguments to TopicCommandIntegrationTest. Will rerun.
