             Summary: 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


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 
constrains 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 containerized of a given framework, without the framework needing 
to explicitly allow for such a parameter.
