Benjamin Mahler created MESOS-5758:
--------------------------------------

             Summary: Add ability to exclude resources from fair sharing.
                 Key: MESOS-5758
                 URL: https://issues.apache.org/jira/browse/MESOS-5758
             Project: Mesos
          Issue Type: Improvement
          Components: allocation, master
            Reporter: Benjamin Mahler
            Assignee: Guangya Liu


Currently, the fair sharing implementation has some caveats when dealing with "scarce" resources:

https://issues.apache.org/jira/browse/MESOS-5377

GPUs have been the first type of first-class "scarce" resource in the system, and consequently we'd like to introduce mechanisms to mitigate the "scarce" resource issues.

The first is a GPU framework capability in MESOS-5634. The second, in this ticket, is to provide the operator with the ability to more generally specify that some resource types (e.g. gpus) should not be fairly shared.
