[jira] [Created] (KAFKA-5056) Shuffling of partitions in old consume fetch requests removed

Todd Palino created KAFKA-5056:
----------------------------------

             Summary: Shuffling of partitions in old consume fetch requests removed
                 Key: KAFKA-5056
                 URL: https://issues.apache.org/jira/browse/KAFKA-5056
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.10.1.0
            Reporter: Todd Palino
            Assignee: 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.
