Recommender system using pig or mahout

Question

I am building a recommend system on Hadoop in a simple way can u give me an opinion on what to use to build this recommendation system.

I would like to use Apache pig or Apache mahout.

In my data set i am having

book_id,name,publisher
user_id,username
book_id,user_id,rating

i have my data in c.s.v format

so can you please suggest me which technology to use to produce item based and user based recommendation system.

Answer 1

Apache Mahout will provide you with a off-shelf recommendation engine based on collaborative filtering algorithms.

With Pig you will have to implement those algorithms yourself - in Pig Latin, which may be a rather complex task.
