Hi Pat,
Does Harness compile against the mahout trunk + MAHOUT-1464.patch
(cooccurance)? I have a patched up branch of the mahout trunk with basically a
gutted MAHOUT-1464.patch- just something that defines
org.apache.mahout.cf.CooccurrenceAnalysis and compiles (so i wouldn't be able
to run Harness right now anyways). I think the changes from MAHOUT-1529 are
causing my problems- the errors are from DrmLike stuff:
[ERROR]
/home/andy/sandbox/harness/src/main/scala/org/apache/mahout/drivers/IndexedDataset.scala:40:

[INFO] case class IndexedDataset(matrix: DrmLike[Int], rowIDs:

Thanks,

> Summary: Build an I/O model that can replace sequence files for
> import/export
> Key: MAHOUT-1568
> URL: https://issues.apache.org/jira/browse/MAHOUT-1568
> Project: Mahout
> Issue Type: New Feature
> Components: CLI
> Environment: Scala, Spark
> Reporter: Pat Ferrel
> Assignee: Pat Ferrel

>
> Implement mechanisms to read and write data from/to flexible stores. These
> will support tuples streams and drms but with extensions that allow keeping
> user defined values for IDs. The mechanism in some sense can replace Sequence
> Files for import/export and will make the operation much easier for the user.
> In many cases directly consuming their input files.
>
> Start with text delimited files for input/output in the Spark version of
> ItemSimilarity
>
> A proposal is running with ItemSimilarity on Spark which and is documented on
> the github wiki here: https://github.com/pferrel/harness/wiki
>
> Comments are appreciated
