---------------------------------------

             Summary: DRF allocator should take into account past allocations 
when determining an ordering so frameworks are not starved.
                 Key: MESOS-1086
                 URL: https://issues.apache.org/jira/browse/MESOS-1086
             Project: Mesos
          Issue Type: Bug
          Components: master
            Reporter: Benjamin Hindman
            Priority: Critical


The DRF allocator (master/drf_sorter.hpp|cpp) currently only uses a framework's 
share to determine an ordering for allocating resources. When there are very 
few resources to go around it's possible that a framework will get allocated 
resources (making it have a dominant share larger than others), use those 
resources, then return those resources (making it's dominant share equal to the 
share of others), and then get reallocated the resources _again_ because its 
dominant share is equal to others. This can cause starvation for frameworks.
