Hi all,
I am newbie in collaborative filtering.I want to implement collaborative filtering algorithm(need
to find top 10 recommended products) using Spark and Scala.I have a rating dataset where userID
& ProductID are String type.

UserID                   ProductID             Rating
b3a68043-c1      p1-160ff5fDS-f74           1
b3a68043-c2      p5-160ff5fDS-f74           1
b3a68043-c0      p9-160ff5fDS-f74           1

I tried ALS algorithm using spark MLlib.But it support rating userID & productID only
Integer type.How can I solve this problem?

Thanks In Advance
