IIRC you could always overcommit in Mesos using DRF weights and accepting resource offers in your application. I could be wrong.
The larger point is that Mesos introduced a new, exciting way to do truly distributed allocation (where the cluster manager (i.e., Mesos) and various applications coordinated and cooperated in how they use computing resources). In contrast, Kubernetes is centralized, pretty vanilla, and I would love to know what new ideas it has introduced (from an algorithmic and architecture perspective).
