Description

In KAFKA-2978, we found a bug which prevented the consumer from fetching some assigned partitions. Our system tests didn't catch the bug because we only assert that some messages from any topic are consumed after rebalancing. We should strengthen these assertions to ensure that each partition is consumed.
