@Karthick Raja,

Check this line in your code

RatingsBreakdown.py line 12, in mapper_get_ratings

(userID, movieID, rating, timestamp ) = line.split('\t')

The line should have exactly 4 values else you may get the issue 'ValueError: need more than 2 values to unpack' . Check the input or add a validation

if len(line.split('\t')) == 4:
	(userID, movieID, rating, timestamp ) = line.split('\t')
