Saikat Kanjilal commented on MAHOUT-1464:
-----------------------------------------
We have a cluster at work , however I'm not sure if I can actually use it, do
we have an AWS account for mahout that I can use, I think this might be a good
opportunity for us to get one for mahout.

> Create a version of RowSimilarityJob that runs on Spark. Ssc has a prototype
> here: https://gist.github.com/sscdotopen/8314254. This should be compatible
> with Mahout Spark DRM DSL so a DRM can be used as input.
> Ideally this would extend to cover MAHOUT-1422 which is a feature request for
> RSJ on two inputs to calculate the similarity of rows of one DRM with those
> of another. This cross-similarity has several applications including
> cross-action recommendations.
