Re: Recommendations using Spark

[Jorge Machado]

Hello anjali, 

You can Start here : org.apache.spark.mllib.recommendation

Them you should build a “recomender”  you need to transform your trainData into 
Rating objects them you can train a model  with for example : val model = 
ALS.trainImplicit(trainData, 10, 5, 0.01, 1.0)

The question itself is very vague.

You might want to use this slide as a starting point

Alternating least squares takes  an RDD of (user/product/ratings) tuples
and the resulting Model provides predict(user, product) or predictProducts
methods among others.
