> Hi mahout.  I'd like to create an umbrella JIRA for allowing more runtime flexibility for reading different types of input formats for all mahout tasks. 
> Specifically, I'd like to start with the FreeTextRecommenderAdapeter, which typically requires:
> 1) Hashing text entries into numbers
> 2) Saving the large transformed file on disk
> 3) Feeding it into classifieer 
> Instead, we could build adapters into the classifier itself, so that the user
> 1) Specifies input file to recommender
> 2) Specifies transformation class which converts each record of input to 3 column recommender format
> 3) Runs internal mahout recommender directly against the data
> And thus the user could easily run mahout against existing data without having to munge it to much.
> This package might be called something like "org.apache.mahout.adapters", and would over time provide flexible adapters to the core mahout algorithm implementations, so that folks wouldnt have to worry so much about vectors/csv transformers/etc... 
> Any thoughts on this?  If positive feedback I can submit an initial patch to get things started.
