When I try to start my mesos cluster without root access, I got the error in the mesos slave:
Log file created at: 2018/02/17 06:57:48
Running on machine: ubuntu
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
E0217 06:57:48.811517 46316 main.cpp:468] EXIT with status 1: Failed to initialize systemd: Failed to create systemd slice ‘mesos_executors.slice’: Failed to write systemd slice `/run/systemd/system/mesos_executors.slice`: Failed to open file ‘/run/systemd/system/mesos_executors.slice’: Permission denied
My mesos cluster consists of three nodes, all the slave host got this error. So I started my mesos cluster with root access in mesos master. It worked.

I think it depends on the version you are using? – user1870400 Mar 07 '18 at 16:51

Perhaps, Best to try it in your own environment. – Yitian Zhang Mar 08 '18 at 06:53

You'll want to run mesos-agent with --no-systemd_enable_support if you don't want to provide it root access and you are okay without the provided systemd support.

Are you sure? I got different answers from different community members. – user1870400 Feb 06 '17 at 10:54

Obviously, you need root access to build Apache Mesos. But once you have it just '.tar' it and 'untar' it on the other users. I have set-up 4 node cluster in mesos. I am not sure whether all functionalities of Mesos would work but was able to run Spark applications on it. – Kool Feb 07 '17 at 11:29
