Notes
If the custom executer would be running under the mesos containerizer. The default isolation configuration in mesos is to tight. For the first shot, change the isolation to:
MESOS_ISOLATION=filesystem/linux,docker/runtime
My mesos-compose framework will use the docker containerizer. These should work out of the box.
