-----------------------------------

             Summary: Address comments about /etc/pam.d/su
                 Key: SPARK-43369
                 URL: https://issues.apache.org/jira/browse/SPARK-43369
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Docker
    Affects Versions: 3.5.0
            Reporter: Yikun Jiang


echo "auth required pam_wheel.so use_uid" >> /etc/pam.d/su &&

I am unsure what this is for? 😕 As far as I can tell, this means that only members of the administrative group wheel (or 0 if there is no wheel) can switch to another user using the su command. That might make sense on a regular multi-user system, but I am unsure why it would matter for a container.
