--------------------------------
SUCCESS: Integrated in Mahout-Quality #2733 (See
[https://builds.apache.org/job/Mahout-Quality/2733/])
MAHOUT-1541, MAHOUT-1568, MAHOUT-1569 refactoring the options parser and option
defaults to DRY up individual driver code putting more in base classes,
tightened up the test suite with a better way of comparing actual with correct
(pat: rev a80974037853c5227f9e5ef1c384a1fca134746e)

> 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 and is documented on the
> github wiki here: https://github.com/pferrel/harness/wiki
> Comments are appreciated
