Cameron resolved KAFKA-7887.
----------------------------
Resolution: Duplicate
> Transaction Producer hanging when commiting/aborting transaction after a
> broker failure
> ---------------------------------------------------------------------------------------
>
> Key: KAFKA-7887
> URL: https://issues.apache.org/jira/browse/KAFKA-7887
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 2.0.1
> Reporter: Cameron
> Priority: Major
>
> I have observed that when a broker fails, the issue with transactional
> producer hanging while trying to commit and/or abort transaction still
> persists
> Within TransactionalRequestResult.class lines 36-42
> {code:java}
> while(!completed) {
> try {
> this.latch.await();
> completed = true;
> } catch (InterruptedException var3) {
> }
> }
> {code}
> this.latch.await() never returns
> Reproducible by bringing down kafka broker while transactional producing is
> sending records
> Suggest (1) calling latch.await() with timeout parameter or (2) allow for
> easier overriding of method by developers to allow them to call await() with
> a timeout
