Marty Kube commented on MAHOUT-1164:
------------------------------------

Yep, the changes look good to me.  Ship it!

So, I did MAHOUT-1163 first.  I think they can go in any order.  But, best 
results will be from 63 and then 64.

These patches are all about getting the RF classifiers to read ARFF files 
without any monkey business. With 63 and 64 the integration and RF code will 
share a common JSON meta-data format.  We'll need one more patch to get RF to 
accept ARFF files.

Longer term future steps are to get all classifiers to accept all format 
supported by the integration modules.

> Add a command line option to generate meta-data in a JSON format.
> This ticket supports the larger goal of making RF classifiers consume the 
> meta-data and sequence files generated by the integration components.  
> MAHOUT-1163 makes RF classifiers read JSON meta-data.  This ticket is to get 
> the ARFF integration to generate the same JSON formatted meta-data.
