[jira] [Commented] (HIVE-24749) Disable user's UDF use SystemExit

    [ https://issues.apache.org/jira/browse/HIVE-24749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17281262#comment-17281262 ] 

okumin commented on HIVE-24749:
-------------------------------

I wonder if it's possible to make SecurityManager pluggable so that administrators can disallow users to run potentially dangerous UDFs.

I know this is too much for this ticket, though.

> If the System.exit() is executed in the user's UDF and using default SecurityManager, it will cause the HS2 service process to exit, that's too bad.
> It is safer to use NoExitSecurityManager which can intercepting System.exit().
