Hi Tao,
Thanks a lot for finding the bug. We are actually rewriting the mirror
maker in KAFKA-1997 with a much simplified solution using the newly added
flush() call in new java producer.
Mirror maker in current trunk is also missing one necessary
synchronization - the UncheckedOffsets.removeOffset is not synchronized. I
am hesitating whether to fix those problems in current trunk or just
waiting for Kafka-1997 to be checked in. If you have a strong opinion
about this, we can probably fix those 2 issues in the trunk. It should be
a small patch but I just don¹t want to people get distracted.
