dajac opened a new pull request, #21305: URL: https://github.com/apache/kafka/pull/21305
This fix allows members to rejoin a consumer group with memberEpoch=0 after being fenced, as specified by KIP-848. Previously, the validation in throwIfConsumerGroupMemberEpochIsInvalid rejected epoch=0 when the member had a higher epoch on the server. Changes: - Add early return for receivedMemberEpoch=0 in validation method - Add unit tests for rejoin in STABLE, UNREVOKED_PARTITIONS, and UNRELEASED_PARTITIONS states - Add integration test for fenced member rejoin flow -- This is an automated message from the Apache Git Service.
