lucasbru opened a new pull request, #15742: URL: https://github.com/apache/kafka/pull/15742
When user-defined rebalance listeners fail with an exception, the expectation is that the error should be propagated to the user as a KafkaExpception and break the poll loop (behaviour in the legacy coordinator). The new consumer executes callbacks in the application thread, and sends an event to the background with the callback result and error if any, [passing the error along with the event here](https://github.com/apache/kafka/blob/98a658f871fc2c533b16fb5fd567a5ceb1c340b7/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AsyncKafkaConsumer.java#L1882) to the background thread, but does not seem to propagate the exception to the user. ### 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.
