> In heterogeneous clusters, tasks sometimes have strong constraints on the type of hardware they need to execute on. The current solution is to use custom resources and attributes on the agents. Detecting non-standard resources/attributes requires wrapping the "mesos-slave" binary behind a script and use custom code to probe the agent. Unfortunately, this approach doesn't allow composition. The solution would be to provide a hook/module mechanism to allow users to use custom code performing resources/attributes discovery.
