Pat Ferrel resolved MAHOUT-1464.
--------------------------------
Resolution: Fixed
WFM on HDFS 1.2.1 Spark compiled to match.
The problem that made this untestable on HDFS seems to be that the read code
was broadcasting something that Kryo did not know how to handle. Fixed this in
the driver/ I/O code and this now works.

> 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.
