> Currently, the mesos containerizer appends the default environment variables of the executor and appends them _after_ any environment that were over-ridden by an isolator. This is problematic e.g., if the CNI isolator over-rides {{LIBPROCESS_IP}} in an overlay network. The containerizer would give the executor environment variables more preference meaning that the container would end up inheriting the IP address of the agent!
