[jira] Created: (HIVE-1614) UDTF json_tuple should return null row
when input is not a valid JSON string
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.
