-----------------------------------
Summary: HS2 should disable local query execution
Key: HIVE-4470
URL: https://issues.apache.org/jira/browse/HIVE-4470
Project: Hive
Issue Type: Bug
Components: HiveServer2
Reporter: Thejas M Nair
Hive can run queries in local mode (instead of using a cluster), if the size is
small. This happens when "hive.exec.mode.local.auto" is set to true.
This would affect the stability of the hive server2 node, if you have heavy
query processing happening on it. Bugs in udfs triggered by a bad record can
bring down the server.
By default, HS2 should set these parameters to disallow local execution or send
and error message if user tries to set these.
