> We are adding per-queue Ordering policies and comparator configurations to
> the Capacity Scheduler. These will need to be surfaced in Ambari.
> Both these configurations need to be surfaced in the Capacity Scheduler View:
> (1) Display name in UI: Ordering Policy
> YARN config name:
> yarn.scheduler.capacity.(STANDARD-QUEUE-SPECIFICATION).ordering-policy
> The value will be chosen from a drop down with two possible values:
> * default value - "fifo" (sans-quotes),
> * alternate value - "fair" (sans-quotes)
> Open Q: should also accept a fairly long string value (sufficient for fully
> qualified java classnames)
> (2) Display name in UI: Enable Size Based Weight Ordering
> YARN config name:
> yarn.scheduler.capacity.(STANDARD-QUEUE-SPECIFICATION).ordering-policy.fair.enable-size-based-weight
> The only time this property needs to be set is when (1) is set to 'fair'.
> When (1) is set to 'fifo', then this property should not be available in the
> UI.
> The possible values are:
> * default value - "false" (sans-quotes)
> * alternate value "true" (sans-quotes)
