-------------------------------

Might be worth exploring using an external store as well to preserve node manager state (currently lost when nodemanager goes done).

> Mesos allows a framework to dynamically reserve the resources offered to it, so that if a task launched on reserved resources dies, the framework that reserved those resources will immediately get offered back the same reserved resources, without any other framework (under a different role) getting a chance to use them. http://mesos.apache.org/documentation/latest/reservation/ This would be valuable if the user truly wanted to guarantee resources on a node once they have started using it. On a related note, we should also support quota, for minimum resource guarantees that are not tied to particular nodes: http://mesos.apache.org/documentation/latest/quota/
