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

    Attachment: yarn-482.patch

Here is a preliminary patch that
# Renames SchedulingMode to SchedulingPolicy, as policy seems to be more apt name
# Extends setting SchedulingPolicy to intermediate queues
# Fixes previously broken assignContainer() hierarchy to include intermediate queues

> FS allows setting {{SchedulingMode}} for leaf queues. Extending this to non-leaf queues allows using different kinds of fairness: e.g., root can have three child queues - fair-mem, drf-cpu-mem, drf-cpu-disk-mem taking different number of resources into account. In turn, this allows users to decide on the scheduling latency vs sophistication of the scheduling mode.
