Jun Rao commented on KAFKA-376:
-------------------------------
Actually, there is one other issue:
In readMessageSet(topic: String, partition: Int, offset: Long, maxSize: Int,
fromFollower: Boolean), could we make sure that actualSize is always >=0 ?
> expose different data to fetch requests from the follower replicas and
> consumer clients

> Currently, the broker always uses highwatermark to calculate the available
> bytes to a fetch request, no matter where the request is from. Instead, we
> should use highwatermark for requests coming from real consumer clients and
> use logendoffset for requests coming from follower replicas.
