--------------------------------------
Summary: Support standard ARRAY_AGG
Key: HIVE-15977
URL: https://issues.apache.org/jira/browse/HIVE-15977
Project: Hive
Issue Type: Sub-task
Reporter: Carter Shanklin
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.
