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

Certain class of tasks might have a need to be scheduled on the same slave (esp
needing shared persistent volumes, MESOS-3421). Instead of dedicating a slave
to a framework, the framework can make a very good determination if it had
exposure to both available as well as total resources.

Doesn't the framework already know which tasks of it are already running on a
given slave? Why does the offer have to contain this information?
> Expose total resources of a slave in offer for scheduling decisions

> Issue Type: Improvement
> Components: general

> Reporter: Anindya Sinha
> Assignee: Anindya Sinha
> Priority: Minor

> To effectively schedule certain class of tasks, the scheduler might need to
> know not only the available resources (as exposed currently) but also the
> maximum resources available on that slave. This is specifically true for
> clusters having different configurations of the slave nodes in terms of
> resources such as cpu, memory, disk, etc.
