Description

Markus Weimer suggested:

"... In REEF-runtime-YARN, we allow users to use native YARN resource requests in addition to the EvaluatorRequest interface ... we could expose the resource offers to a application-provided EventHandler. That way, REEF provides a abstraction for resource requests that is portable, but also allows code to circumvent this abstraction in a sane way."

We can set up an event handler such that resourceOffers() callback coming from Mesos is exposed to REEF users.
