-----------------------------------
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.
