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

Some minor comments about configuration part by index: 1) done 2) done 3) done - see below bq. Do you think is it better to make property in queue-name.ordering-policy.policy-name.property-key?... Now that there is not proper composition only one policy can be active at a time and it shouldn't be necessary to namespace config items this way. At the same time, I could see us getting back to proper composition at some point, where this would be helpful. I've implemented it as a prefix convention in the policy instead of constraining the contents of the map in the capacity scheduler configuration. This is because we still support passing a class name as the policy type, which would make the configurations for class name based items unwieldy. It would also allow us to have shared configuration items between policies if we do end up with proper composition again. The end result of the configuration was as you suggested 4) done 5) done bq. FairOrderingPolicy: all 3 done bq. Findbugs warning? Failed to stage change, so it didn't make it into patch, should be there now.
