Wang Haoran commented on MESOS-1860:
------------------------------------
I have some comments here which are implements in our project like mesos:
1. we divide the nodes in to different resource pool using the "role " like
mesos
2. the framework register with a role constraint.
> Give more control to the Mesos Administrator

> Key: MESOS-1860
> URL: https://issues.apache.org/jira/browse/MESOS-1860
> Project: Mesos
> Issue Type: Story
> Components: framework, master, slave
> Reporter: Chris Heller
> Labels: design, features
>
> Mesos currently relies on a framework to:
> - discard offers which don't match attributes that the framework finds
> desirable
> - specify which role a given resource request will belong to.
> This creates a scenario where to restrict a framework to a certain subset of
> slaves within a cluster one must unfortunately modify the framework.
> This story is meant to open a discussion on how Mesos could be modified so
> that:
> - an administrator could define attribute constraints which would apply to a
> given framework, without requiring framework support (i.e. an administrator
> could specify that the spark framework only accept offers with an attribute
> of 'appclass=spark' or any other predicate).
> - an administrator could classify framework requests into a given role, again
> without framework support (i.e. an administrator could specify that the spark
> framework requests for 'cpu(*)' become requests for 'cpu(spark)')
> Taking things a step further, how might it be possible that attribute
> constraints and request classifications could be setup for a single instance
> of a framework (i.e. a user fires up spark-shell with a given attribute
> constraint -- without needing to modify spark-shell to support attribute
> constraints)?
> This functionality could apply even deeper: an administrator should be able
> to specify the containerizer of a given framework, without the framework
> needing to explicitly allow for such a parameter.
