> One of the primary points of confusion about Mesos is the mechanism it provides frameworks
to acquire new resources (e.g. cpu, ram, etc.). Currently, frameworks receive callbacks with
resource offers which they can accept (entirely or only a portion) or reject. When they accept
them, they provide a task to be executed on those resources.
> Many engineers we have spoken to have said that they would find it more intuitive to
provide their executable up front with a description of which and how many resources they
want, and then have mesos do the scheduling.
> I propose that Mesos should ship with a framework that can very easily be installed and
run by new users, and this framework should accept "Launch Job Requests" expressed via some
language that describes the resource requirements and where to find the executable for the
tasks in the job.
