> Project: Hive
> Issue Type: New Feature
> Components: UDF
> Affects Versions: 0.12.0, 0.13.0
> Environment: all
> Reporter: Ming Ma
> Assignee: Navis

> https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFJson.java#L250
> this line should be out of the for-loop
> For example
> json = '{"h":[1, [2, 3], {"i": 0}, [{"p": 11}, {"p": 12}, {"pp": 13}]}'
> get_json_object(json, '$.h[*][0]') should return back the first node(if
> exists) of every childrenof '$.h'
> which specifically should be
> [2,{"p":11}]
> but hive returns only
> 2
> because when hive pick the node '2' out, the tmp_jsonList will change to a
> list only contains one node '2':
> [2]
> then it was assigned to variable jsonList, in the next loop, value of i would
> be 2 which is greater than the size(always 1) of jsonList, then the loop
> broke out.
