Need advice for Implementing classification algorithms in MapReduce

[unmesha sreeveni <un...@gmail.com>]

In-order to learn MapReduce algorithm,I usually try it from scratch.
What I follow is for classification algorithms-

*First I build a model *
*hadoop jar myjar.jar edu.ModelDriver <Modelinput> <Modeloutput>*

*secondly I will write a prediction class in MR*
*hadoop jar myjar.jar edu.PredictDriver <Testinput> <TestOutput>
<Modeloutput>*

  *<Modeloutput> is supplied as an argument to get the model results for
prediction.*

Is this a better way ?

or Should I follow the below way -

*hadoop jar myjar.jar edu.Driver train="traininput.txt"
test="testinput.txt" output=outputlocation*


Which is the standard way?
Please suggest
