Carlo Curino commented on YARN-1051:
------------------------------------
I attach a technical report that reports some compelling experimental evidence
to support this feature. The report provides a summary of
our earlier implementation, and is our general blueprint of a solution, the
actual code is being completely rewritten to clean-up and make
easier to review/evolve. With respect to what's in the report, we are adding
policies to enforce user quotas (YARN-1711), and we are leveraging
more of the ResourceRequest and ResourceCalculator expressivity.
> YARN Admission Control/Planner: enhancing the resource allocation model with
> time.

> In this umbrella JIRA we propose to extend the YARN RM to handle time
> explicitly, allowing users to "reserve" capacity over time. This is an
> important step towards SLAs, long-running services, workflows, and helps for
> gang scheduling.
