-------------------------------------
Sorry for that I didn't notice that the contribution flow has changed. And I
already sent a PR for this issue, but couldn't assign it to myself.
Hi [~jqin],
If you have free time, please help me to verify if the issue in mailing list
thread I mentioned is a bug, and should it be fix like I suggested?
If this is a bug, and the solution is good to you, please assign this Jira
issue to me. Thanks.

> As the survey in this mailing list thread [1], kafka server will bind the
> error with topic-partition list when it handles `AddPartitionToTxnRequest`.
> So when the request body contains no topic-partition, the error won't be sent
> back to kafka producer client. Moreover, it producer internal api, it always
> check if `newPartitionsInTransaction` is empty before sending
> ADD_PARTITIONS_TO_TXN request to kafka cluster. We should apply it as well if
> you need to explicitly call it in the first commit phase of two-phase commit
> sink.
