Arun C Murthy commented on YARN-1051:
-------------------------------------

Thanks [~subru], I'll take a look at the update.

One thing I've mentioned to [~curino] offline is that I think we are better of relying on
enhancing/reducing *priorities* for applications to effect reservations rather than relying
on adding/removing queues.

Priorities within the same queue is an often requested feature anyway - that way we can solve
multiple goals (operational-feature/reservations) with the same underlying mechanism i.e.
priorities.

> 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.
