Ted Dunning commented on MAHOUT-1464: ------------------------------------- {quote} Scary adding to Dmitriy's code though so I'll invite him to look at it. Added a couple tests but I don't see many for SparkEngine. {quote} We don't have author tags. This is *our* code now and we all have to feel a bit of ownership and entitlement. Go for it. > Cooccurrence Analysis on Spark > ------------------------------ > > Key: MAHOUT-1464 > URL: https://issues.apache.org/jira/browse/MAHOUT-1464 > Project: Mahout > Issue Type: Improvement > Components: Collaborative Filtering > Environment: hadoop, spark > Reporter: Pat Ferrel > Assignee: Pat Ferrel > Fix For: 1.0 > > Attachments: MAHOUT-1464.patch, MAHOUT-1464.patch, MAHOUT-1464.patch, > MAHOUT-1464.patch, MAHOUT-1464.patch, MAHOUT-1464.patch, run-spark-xrsj.sh > > > Create a version of Cooccurrence Analysis (RowSimilarityJob with LLR) that > runs on Spark. 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.
