Hi, I have been using spark to implement our recommendation algorithm, for which it was hard to get secondary sort by value, thus, I have implemented this algorithm with the help of hive. I think, spark does not support secondary sort yet.
I have recently implemented the same recommendation algorithm in crunch running on spark with using crunch secondary sort API. I am wondering how to implement secondary sort in crunch running on spark. Anybody can give me some explanations about the implementation of secondary sort in crunch spark? thanks, - Kidong.
