I think I didn't explain clear enough and sorry for that. The example showed before is a part of my data.
Each line is a user profile, for example, the first row is the features of a user. And I want to apply k-means to this data. I need to create a file saves all users profile as sparse vector and put them in mahout k-means algorithm, how can I do that? Thanks for your advice!
