             Summary: 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.
