get_json_object does not support JSON array at the root level
-------------------------------------------------------------
Key: HIVE-1575
URL: https://issues.apache.org/jira/browse/HIVE-1575
Project: Hadoop Hive
Issue Type: Improvement
Components: UDF
Affects Versions: 0.7.0
Reporter: Steven Wong
Currently, get_json_object(json_txt, path) always returns null if json_txt is
not a JSON object (e.g. is a JSON array) at the root level.
I have a table column of JSON arrays at the root level, but I can't parse it
because of that.
get_json_object should accept any JSON value (string, number, object, array,
true, false, null), not just object, at the root level. In other words, it
should behave as if it were named get_json_value or simply get_json.
