     [ https://issues.apache.org/jira/browse/KAFKA-13303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

-------------------------------
    Affects Version/s: 2.4.0
                       2.5.0

> RoundRobinPartitioner broken by KIP-480
> ---------------------------------------
>
>                 Key: KAFKA-13303
>                 URL: https://issues.apache.org/jira/browse/KAFKA-13303
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 2.4.0, 2.5.0, 2.4.1, 2.5.1
>            Reporter: Jon McEwen
>            Priority: Minor
>
> Since KIP-480 Sticky Partitioning, the RoundRobinPartitioner doesn't behave correctly.  An additional call to `partition()` on new batch leads to partitions being skipped.
>  
> I have a fix that I would like to contribute, but I need help getting started as a contributor, e.g. for basic things like formatting the code.
