Hive does not support multi-distinct in one query.
We have implemented multi-distinct based on hive 0.4.2rc to our demand.
We don't know that if Hive is intresting in this feature.

Hi all,
I read the tutorial of Hive, and it says that "no two aggregations can have
different DISTINCT columns". Could anyone tell what is the reason ? Does the
following Distinct will been translate to map-reduce job or just do it
locally ?
INSERT OVERWRITE TABLE pv_gender_agg
SELECT pv_users.gender, count(DISTINCT pv_users.userid), count(DISTINCT
pv_users.ip)
FROM pv_users
GROUP BY pv_users.gender;
