Subject [jira] [Commented] (HIVE-4073) Make partition by optional in over clause
Date Thu, 28 Feb 2013 03:07:13 GMT


Brock Noland commented on HIVE-4073:


When OVER() with no partition column is specified, we will partition by some constant. In
that case, there is only a need for a single reducer.  Should this change force the single
reducer? Not sure how how I would do that yet.
