Thejas M Nair created HIVE-4470: ----------------------------------- 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. -- This message is automatically generated by JIRA.
