> Right now in MockConsumer we shall return illegal state exception when the buffered records are not able to find corresponding assigned partitions. This is not the case for KafkaConsumer where we shall just not return those data during `poll()` call. This inconsistent behavior should be fixed.
> Note that if we are going to take this fix, the full unit tests need to be executed to make sure no regression is introduced, as some tests are potentially depending on the current MockConsumer behavior.
