showuon opened a new pull request, #14192: URL: https://github.com/apache/kafka/pull/14192
Currently, when consumer startup, there will be a log message said: ``` [2023-08-11 15:47:17,713] INFO [Consumer clientId=console-consumer, groupId=console-consumer-28605] Request joining group due to: rebalance failed due to 'The group member needs to have a valid member id before actually entering a consumer group.' (MemberIdRequiredException) (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator) ``` It confused users and make them think there's something wrong in the consumer application. Since `MemberIdRequiredException` is an expected transient exception, we could improve the log into a more informative way without exception words. After change: ``` [2023-08-11 15:42:11,821] INFO [Consumer clientId=console-consumer, groupId=console-consumer-96226] Request joining group due to: The group member needs to have a valid member id before actually entering a consumer group. ``` ### 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.
