[jira] Updated: (MAHOUT-548) Add support for CSV for Vector IO
Posted by "Grant Ingersoll (JIRA)" <ji...@apache.org>.

Grant Ingersoll updated MAHOUT-548:
-----------------------------------
Attachment: MAHOUT-548.patch
Here's a first crack at support for reading in and putting out CSV. The output comes via the VectorDumper, but we really should have a more generic framework for output, me thinks. Input is handled through a new utils package called csv that defines a CSVVectorIterable. It uses Commons CSV (published via Solr into Maven)
There's also a couple of other Iterables for things I had started on that I should have posted separately but got mixed in.

Maven note:
I am not sure if it is absolutely unavoidable to bring solr dependency in but if it is needed, please read MAHOUT-622, I am trying to fix instances like this there.
Thanks.
