title: Mesos applications, why not use Marathon for everything?
body: <p>I see Mesosphere building all kinds of applications on the Mesos Framework like Hadoop, Kubernetes, etc. but since there is the Marathon applications for long-running services, why not just use that? E.g. why not setup Kubernetes nodes on a bunch of Marathon services? Why implement Kubernetes directly on Framework API? Because scheduling is more efficient that way? Same question goes for Jenkins implementation, why not just run Jenkins master/slaves on top of Marathon...</p>
