Well, it needs to be in comma-separated or tab-separated format, with fields
"user ID" then "item ID" (optionally followed by preference value) on each
line. Is there something more?

Hi,

open a shell, cd to the directory where you downloaded the dataset and run:

tar xvfz million-ml-data.tar__0.gz
sed s/::/,/g ratings.dat > ratings.csv

ratings.csv should then be in the correct format to be used with the job.
