Edward Capriolo commented on HIVE-4470: --------------------------------------- {quote} By default, HS2 should set these parameters to disallow local execution or send and error message if user tries to set these. {quote} I do not agree with this. I can understand the argument for making the default off, but explicitly disabling it is too extreme. > 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 > potentially add very heavy load making the server inaccessible. > 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.
