Carlo Curino commented on YARN-5676:
------------------------------------
For very large queue structures, it is convenient to specify a policy for a
subset of the queues (e.g., large/prod queues), and use something like the
{{HashBasedRouterPolicy}} to automatically map all the small to subclusters.
This is better than any of the randomized policies because the mapping between
queue and sub-cluster tends to be more stable, hence there is some better
chance for locality.
I will post the patch soon (testing now).
> Add a HashBasedRouterPolicy, that routes jobs based on queue name hash.
