IMDb Dataset Details Each dataset is contained in a gzipped, tab-separated-values (TSV) formatted file in the UTF-8 character set. In this challenge, we'll use MovieLens 100K Dataset. We aim the model to give high predictions for movies watched. In the first part, you'll first load the MovieLens data (ratings.csv) into RDD and from each line in the RDD which is formatted as userId,movieId,rating,timestamp, you'll need to map the MovieLens data to a Ratings object (userID, productID, rating) after removing timestamp column and finally you'll split the RDD into training and test RDDs.
