Avinash Sridharan commented on MESOS-5533:
------------------------------------------
Interesting .. just to make sure can you start it with the
--network_cni_plugins_dir=VALUE and --network_cni_config_dir=VALUE flags.
Without these flags the `network/cni` isolator is effectively a no-op.
[~karya] we were observing this problem when we running tests and launching
containers or just bringing up the Agent was failing?
> Agent fails to start on CentOS 6 due to missing cgroup hiearchy

>
> With the network CNI isolator, agent now _requires_ cgroups to be installed
> on the system. Can we add some check(s) to either automatically disable CNI
> module if cgroup hierarchies are not available or ask the user to
> install/enable cgroup hierarchies.
> On CentOS 6, cgroup tools aren't installed by default.
