Hi, @Hansel Chung As I checked, if --swithc_user=true (default variable is true) when you launch Mesos agent, executor would call os::setuid and os::setgroups before launch your tasks. But the shell environment may not set. (I remember we have a ticket for this.) You could use `id` as your task command to verify if user set correctly.
