Create framework that provides a high level resource request language
---------------------------------------------------------------------
Key: MESOS-156
URL: https://issues.apache.org/jira/browse/MESOS-156
Project: Mesos
Issue Type: New Feature
Components: framework
Reporter: Andy Konwinski
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.
