Subject how to implement ALS with csv file? getting error while calling Rating class
Date Sun, 06 Mar 2016 16:22:50 GMT
I am new to apache Spark, and I want to implement the Alternating Least
Squares algorithm. The data set is stored in a csv file in the format:
*Name,Value1,Value2*.

When I read the csv file, I get
*java.lang.NumberFormatException.forInputString* error because the Rating
class needs the parameters in the format: *(user: Int, product: Int,
rating: Double)* and the first column of my file contains *Name*.

Please suggest me a way to overcome this issue.
