Dana Powers commented on KAFKA-3442:
------------------------------------
In all prior broker releases clients check the response for a "partial" message
-- i.e. the MessageSetSize is less than the MessageSize. This follows this
statement in the protocol wiki:
"As an optimization the server is allowed to return a partial message at the
end of the message set. Clients should handle this case."
So in this case the client is checking for a partial message, not an error code.
> FetchResponse size exceeds max.partition.fetch.bytes

> Produce 10000 byte message to topic foobar
> Fetch foobar w/ max.partition.fetch.bytes=1024
> Test expects to receive a truncated message (~1024 bytes). 0.8 and 0.9 pass
> this test, but 0.10 FetchResponse has full message, exceeding the max
> specified in the FetchRequest.
> I tested with v0 and v1 apis, both fail. Have not tested w/ v2
