--------------------------------------
Summary: new coordinator does not support v0-v2
TxnOffsetCommitRequest when using CONSUMER group
Key: KAFKA-18060
URL: https://issues.apache.org/jira/browse/KAFKA-18060
Project: Kafka
Issue Type: Bug
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
TxnOffsetCommitRequest versions v0-v2 do not include a member ID, causing
ConsumerGroup#validateOffsetCommit [0] to throw an UnknownMemberIdException.
This prevents the old producer from calling sendOffsetsToTransaction.
Note that TxnOffsetCommitRequest versions v0-v2 are included in KIP-896 [1], so
it seems the new coordinator should support that operations
