Does Cgroups implementation require kerberos enabled cluster? Apache documentation says security is not needed. Hortonworks says it needs kerberos enabled cluster? Which is correct?

[#1]

We are running our cluster on CentOS 7. We have a plan to implement yarn new features such as CPU isolation. CPU isolation needs cgroups. May i implement cgroups without implementing Kerberos?
