Magnus Edenhill commented on KAFKA-1588:
----------------------------------------

[~guozhang] Why would this fix require a protocol change? It is already an 
array of Topics+partitions in the OffsetRequest and all the broker needs to do 
is honour the contents and order of that list and respond accordingly, which 
should be a broker implementation detail only and not affect the protocol 
definition, right?

> Offset response does not support two requests for the same topic/partition 
> combo

> When performing an OffsetRequest, if you request the same topic and partition 
> combination in a single request more than once (for example, if you want to 
> get both the head and tail offsets for a partition in the same request), you 
> will get a response for both, but they will be the same offset.
> We identified that the problem is that when the offset response is assembled, 
> a map is used to store the offset info before it is converted to the response 
> format and sent to the client. Therefore, the second request for a 
> topic/partition combination will overwrite the offset from the first request.
