+Tim Chen (please chime in if I'm missing something) Sorry for the delay, from a quick glance it looks like the DockerContainerizer it a bit less liberal in the setting up of cgroups if they are not mounted on the machine. I'm curious, if you remove "docker" from the containerizers flag, does it work?
Otherwise, you can try mount the cgroups manually, as suggested by the error message. Feel free to file a ticket to capture this!
