I work on a user to user recommender for a website using mllib.recommendation. I have created a file (recommends.txt) which contains the top 5 recommendations for each user id. The file's form(recommends.txt) is something like this (user::rec1:rec2:rec3:rec4:rec5):
/**file's snapshot**/ 5823::944::10030::27::1047::2891::836 14::2097::10030::2427::1874::2018::5804 2726::6557::2776::2959::6619::2018::4466 6367::6557::9359::2726::2542::10159::3574 5804::27::2891::9359::944::1599::1047 1044::944::6557::2542::4737::1866::1874 /**file's snapshot**/ My Question : So I already have the users.sql file which contains the (id,names) and i want to shape recommends.txt to : Bob::Michael::Peter:Steve:Bill::George how can i easily do this?
