The partitioner gets the number of positions with every call. So it can be
written to respect that number...

> It would be helpful to be able to specify a custom partitioner for shuffle
> steps. This would users allow to control how their data is distributed across
> the cluster. Especially in situations where the number of data records is
> equal to the number of slots it might be a possibility to avoid skewed data
> distributions due to the default hashing function.
