brandboat opened a new pull request, #16372: URL: https://github.com/apache/kafka/pull/16372
related to https://issues.apache.org/jira/browse/KAFKA-16975 The error message of creating "__cluster_metadata" by admin is "Authorization failed.". That could confuse users that it implies you "can" create it in using root. While creating this topic is prohibited. This pr corrected the error code and error message in KafkaApis when user creating __cluster_metadata topic. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
