UDTF json_tuple should return null row when input is not a valid JSON string
----------------------------------------------------------------------------

                 Key: HIVE-1614
                 URL: https://issues.apache.org/jira/browse/HIVE-1614
             Project: Hadoop Hive
          Issue Type: Bug
            Reporter: Ning Zhang
            Assignee: Ning Zhang


If the input column is not a valid JSON string, json_tuple will not return 
anything but this will prevent the downstream operators to access the left-hand 
side table. We should output a NULL row instead, similar to when the input 
column is a NULL value.
