Sean Owen resolved SPARK-17185.
-------------------------------
    Resolution: Won't Fix

I think the point is reasonable but I'm pretty sure we would not change the API or even introduce deprecations plus new methods just for this.

>            Reporter: Xiang Gao
>            Priority: Minor

> In {{RDD}}, {{groupByKey}} is used to generate a key-list pair and  {{aggregateByKey}} is used to do aggregation.
> In {{Dataset}}, aggregation is done by {{groupBy}} and {{groupByKey}}, and no API for key-list pair is provided.
> The same name {{groupBy}} is designed to do different things and this might be be confusing. Besides, it would be more convenient to provide API to generate key-list pair for {{Dataset}}.
