Mahout Naive Bayes CSV Classification

I have these 2 CSV files:

  1. train-set.csv
  2. test-set.csv

Both of them are in the same structure (with different content) and similar to this example :

enter image description here

Each column is a feature and the last column - class, is the name of the class to predict.

.

Can anyone please provide a sample code for:

  1. Initializing Naive Bayes with a CSV file (model creation, training, required pre-processing, etc...)
  2. For a given CSV row - predicting a class

Thanks!

BTW -

I'm using Mahout 0.9 and Hadoop 2.4 and iv'e already tried to follow these links:
