>                 Key: SPARK-1672
>                 URL: https://issues.apache.org/jira/browse/SPARK-1672
>             Project: Spark
>          Issue Type: Improvement
>          Components: MLlib
>            Reporter: Tor Myklebust
>            Priority: Minor
>
> The user ought to be able to specify a partitioning of his data if he knows a 
> good one.  It's convenient to have separate partitioners for users and 
> products so that no strange mapping step needs to happen.
> It may also be reasonable to partition the users and products into different 
> numbers of partitions (for instance, to balance memory requirements) if the 
> dataset is tall, thin, and very sparse.
