--------------------------------------------
I used those files here:
http://www.trustlet.org/datasets/downloaded_epinions/ratings_data.txt.bz2
http://www.trustlet.org/datasets/downloaded_epinions/trust_data.txt.bz2
RunCrossCooccurrenceAnalysisOnEpinions in
org.apache.mahout.cf.examples.Recommendations.scala shows how to run
cross-co-occurrence on these files (code in the patch).

> 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. This cross-cooccurrence has
> several applications including cross-action recommendations.
