Timothy Chen commented on MESOS-4138:
-------------------------------------

The idea of exclusive resources is definitely needed! One question after reading the proposal is, how do we offer exclusive resources like cpusets? Clearly frameworks need to know the difference between shares and sets, but it's not specified in the proposal.

> Propose the concept of exclusivity to resources. An exclusive resource is a) not shared with any other task, b) employs stronger isolation for more predictable performance, and c) is consequently not oversubscribed (if enabled). In contrast to normal resources, exclusive resources have greater resource priority while oversubscribed resources have lower priority. 
> Initial resources that could support the notion of exclusivity include cpu, network egress bandwidth, and IP addresses.
