Phabricator updated HIVE-2689:
------------------------------
Attachment: HIVE-2689.D1083.1.patch
jonchang requested code review of "HIVE-2689 [jira] ObjectInspectorConverters
cannot convert Void types to Array/Map/Struct types.".
Reviewers: JIRA
HIVE-XXXX: Null conversion
In a bunch of places we rely on ObjectInspectorConverters to implicitly
convert types. Unfortunately, an exception will needlessly be thrown if one of
the types is a complex type and the other is a void type. For example,
SELECT ARRAY(ARRAY(), NULL) ...
