Pat Ferrel commented on MAHOUT-1541:
------------------------------------
The mahout-1541 branch in the above PR currently does not build because of core
DSL changes since it was written.
The root issue is that I need DrmLike[Int]s to pass to
CooccurrenceAnalysis.cooccurrence. The CLI reads these from text files. To read
text files I need a SparkContext, which is not a problem. But to write the
output I need an RDD. The DrmLike's that I was keeping used to contain the RDD
but no longer do. A question that is blocking at present is:
1) What is the preferred way to pass around an object with both a DrmLike
interface and an Rdd reference? Should I create this or does it already exist?
I've looked in the PDF doc and the scaladocs but couldn't find the answer.
Therefore I'll create something unless someone has better advice.

> Project: Mahout
> Issue Type: Bug
> Components: CLI
> Reporter: Pat Ferrel
> Assignee: Pat Ferrel
>
> Create a CLI driver to import data in a flexible manner, create an
> IndexedDataset with BiMap ID translation dictionaries, call the Spark
> CooccurrenceAnalysis with the appropriate params, then write output with
> external IDs optionally reattached.
> Ultimately it should be able to read input as the legacy mr does but will
> support reading externally defined IDs and flexible formats. Output will be
> of the legacy format or text files of the user's specification with
> reattached Item IDs.
> Support for legacy formats is a question, users can always use the legacy
> code if they want this. Internal to the IndexedDataset is a Spark DRM so
> pipelining can be accomplished without any writing to an actual file so the
> legacy sequence file output may not be needed.
> Opinions?
