Originally, we make sure consumer `awaitAssignment`, and then produce records. We total send 30 records to 3 topics, and each topic has 30 partitions, so it takes some time to process it. If it exceeds 6 seconds, it'll make the consumer left due to the `max.poll.interval.ms` is set to 6 secs. And then it will delete the logs and then increment the start offset. So, later when the consumer is back, we'll first listOffset, and got the new and unexpected start offset. That's why we sometimes cannot receive expected amount of records. To fix it, I produce records before `awaitAssignment`, and then, I make sure we consume records right after awaitAssignemnt. This will make this test much more reliable. ### 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.
