[~becket_qin] would you mind if I picked this issue up?

>             Project: Kafka
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 0.10.2.1, 1.0.0, 0.11.0.2

> We encountered a problem that some of the legacy log segments contains 
> messages whose offsets are larger than {{SegmentBaseOffset + Int.MaxValue}}.
> Prior to 0.10.2.0, we do not assert the offset of the messages when appending 
> them to the log segments. Due to KAFKA-5413, the log cleaner may append 
> messages whose offset is greater than {{base_offset + Int.MaxValue}} into the 
> segment during the log compaction.
> After the brokers are upgraded, those log segments cannot be compacted 
> anymore because the compaction will fail immediately due to the offset range 
> assertion we added to the LogSegment.
> We have seen this issue in the __consumer_offsets topic so it could be a 
> general problem. There is no easy solution for the users to recover from this 
> case. 
> One solution is to split such log segments in the log cleaner once it sees a 
> message with problematic offset and append those messages to a separate log 
> segment with a larger base_offset.
> Due to the impact of the issue. We may want to consider backporting the fix 
> to previous affected versions.
