Hi, I have JavaPairRDD<String, List<Integer>> and as an example what I want to get.
user_id cat1 cat2 cat3 cat4 522 0 1 2 0 62 1 0 3 0 661 1 2 0 1 query : the users who have a number (except 0) in cat1 and cat3 column answer: cat2 -> 522,611 & cat3->522,62 = user 522 How can I get this solution? I think at first, I should have JavaRDD<List<String>> of user list who are in that column. Thank you Best, yasemin -- hiç ender hiç
