             Summary: Offset response does not support two requests for the same topic/partition combo
                 Key: KAFKA-1588
                 URL: https://issues.apache.org/jira/browse/KAFKA-1588
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8.2
            Reporter: Todd Palino


When performing an OffsetFetchRequest, 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.
