Joe Prasanna Kumar commented on MAHOUT-520:
-------------------------------------------

Drew,

I was just looking at your patch. Couple of observations.

1. type, ng and source are optional parameters in TrainClassifier and by default they are set to the values you have in the script
2. type, ng, source and method are optional params in TestClassifier and are set to the values you have mentioned
3. after checking if HADOOP_HOME is set, should we run TrainClassifier and TestClassifier in parallel mode by setting the method parameter to mapreduce ? If HADOOP_HOME is not, we could just invoke TrainClassifier and TestClassifier without setting those params so it goes into sequential mode ?

regards
Joe.
