---------------------------------
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.
