>                 URL: https://issues.apache.org/jira/browse/HIVE-18711
>             Project: Hive
>          Issue Type: Bug
>          Components: UDF

>            Assignee: Miklos Gergely
>            Priority: Major
> 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.
