Hey all, We (m6d.com) have released a implementation of the rank feature to github:
https://github.com/edwardcapriolo/hive-rank We have a nice description of how it works in our blog: http://www.edwardcapriolo.com/roller/edwardcapriolo/entry/doing_rank_with_hive We are doing some extra-credit string conversion that probably can be optimized for some extra performance if anyone is interested in a fork :) Enjoy all,
