The Hive Programming Book explains how to implement a "collect" function that returns a list (instead of set) of objects…perhaps u can tweak this to return the N number of items in List

Subject: collect_set question
For collect_set is it possible to only collect a few elements and then stop? For example
group by user.
For each user, there could be hundreds of timestamps, but I only need 3 or 4 per user. Is there a way to tell collect_set to stop collecting after it's reached a certain number of elements?
