> Implement a FairOrderingPolicy which prefers to allocate to
> SchedulerProcesses with least current usage, very similar to the
> FairScheduler's FairSharePolicy.
> The Policy will offer allocations to applications in a queue in order of
> least resources used, and preempt applications in reverse order (from most
> resources used). This will include conditional support for sizeBasedWeight
> style adjustment
> Optionally, based on a conditional configuration to enable sizeBasedWeight
> (default false), an adjustment to boost larger applications (to offset the
> natural preference for smaller applications) will adjust the resource usage
> value based on demand, dividing it by the below value:
> Math.log1p(app memory demand) / Math.log(2);
> In cases where the above is indeterminate (two applications are equal after
> this comparison), behavior falls back to comparison based on the application
> id, which is generally lexically FIFO for that comparison
