    Description

      Most common way to implement this is via ordered aggregate which allows users to specify sort specification with group by clause. Some implementations also allow to use these with window functions.

      Since Hive doesn't have concept of ordered aggregates yet, one possibility is to support these only for window functions where sort specification is also taken from window clause.
