[jira] [Created] (MAHOUT-1464) RowSimilarityJob on Spark

Pat Ferrel created MAHOUT-1464:
----------------------------------

             Summary: RowSimilarityJob on Spark
                 Key: MAHOUT-1464
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1464
             Project: Mahout
          Issue Type: Improvement
          Components: Collaborative Filtering
    Affects Versions: 0.9
         Environment: hadoop, spark
            Reporter: Pat Ferrel
             Fix For: 0.9


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.
