Subject [jira] Created: (HIVE-1575) get_json_object does not support JSON array at the root level
Date Fri, 20 Aug 2010 01:40:16 GMT
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.
