Klaus Ma commented on MESOS-4666:
---------------------------------
> For 2) Why do you want exclusive access? Is it because the current isolation
> (resource and security) in Mesos is not
> good/compliant enough or something else?
No. The reason is due to the existing architecture of the service that we wish
to deploy. The constraints for deployment of this service requires n instances
of app1 to be colocated with 1 instance of app2.
[Klaus]: Why not used Marathon to handle such kind of dependency? Currently,
there's no framework's dependency in Mesos; is it possible to handle it by
meta-framework in your prod env?
> Expose total resources of a slave in offer for scheduling decisions

> Key: MESOS-4666
> URL: https://issues.apache.org/jira/browse/MESOS-4666
> Project: Mesos
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.25.0
> 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.
> 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.
