Pat Ferrel commented on MAHOUT-1464: ------------------------------------ My problem is that my cluster is 1.2.1 and to upgrade everything I run on it has to go to H2. Oh bother. I think the best thing is commit this and see it someone will run one of the several included tests on a cluster. It works local and seems to work clustered but the write fails. The write is not part of the core code. Anyway unless someone vetos I'll commit it once I get at least one build integrated test included. > 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: Sebastian Schelter > 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.
