[jira] [Commented] (MESOS-1860) Give more control to the Mesos Administrator

["Wang Haoran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-1860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14390903#comment-14390903 ] 

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.

>             Project: Mesos
>          Issue Type: Story
>          Components: framework, master, slave
>            Reporter: Chris Heller

> 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.
