Sean Owen resolved SPARK-18858.
-------------------------------
Resolution: Invalid
Questions should really go to [email protected]. The Dataset API is
different. I think you will end up using groupBy() and something like
flatMapGroups() to achieve what you want.

> Hi,
> I don´t really know if this is a bug or not.
