---------------------------------
Assignee: Teddy Choi
> Support standard ARRAY_AGG
> --------------------------
>
> Key: HIVE-15977
> URL: https://issues.apache.org/jira/browse/HIVE-15977
> Project: Hive
> Issue Type: Sub-task
> Components: SQL
> Reporter: Carter Shanklin
> Assignee: Teddy Choi
>
> SQL defines array_agg as a function that returns an array given a value
> expression in Section 10.9. Hive has something similar called collect_list.
> The SQL standard array_agg additionally allows sorting by a value expression.
> It would be good to move to the standard and as a first step it might be
> worthwhile to have array_agg as an alias and then to add support for sort
> specifications.
