>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 0.10.1.0
>            Reporter: Todd Palino

> [KIP-74|https://cwiki.apache.org/confluence/display/KAFKA/KIP-74%3A+Add+Fetch+Response+Size+Limit+in+Bytes]
>  deprecated the constructor to {{FetchRequest}} which shuffles the 
> {{requestInfo}} parameter, in favor of round robin reordering logic added to 
> the replica fetcher and the consumer API. However, this was not added to the 
> old consumer {{ConsumerFetcherThread}}, which has resulted in unfair 
> partition fetching since 0.10.1.
> In order to maintain the old consumer, we need to add the removed shuffle to 
> {{buildFetchRequest}} as the topic-partition list for each {{FetchRequest}} 
> is composed.
