[jira] [Created] (HIVE-5438) Introduce different server modes for
error handling in Hive server2

---------------------------------
Summary: Introduce different server modes for error handling in Hive server2
Key: HIVE-5438
URL: https://issues.apache.org/jira/browse/HIVE-5438
Project: Hive
Issue Type: New Feature
Components: HiveServer2
Affects Versions: 0.11.0
Reporter: Xuefu Zhang
Assignee: Xuefu Zhang
Currently Hive handles errors such as divide-by-zero, numeric overflow/iunderflow, type conversion, etc. by putting null values. While the behaviours isn't consistent all the time (see HIVE-5436 as an example), which needs to be addressed, it's desirable to introduce different server modes and allow user to choose different error handling. For instance, instead of null, MAX value may be placed in case of number overflow.
Major databases have such settings. For example, mysql has a setting for data overflow and a setting specifically for divide-by-zero. It's desirable for Hive to give such flexibility to the user.
