Karthik Kambatla commented on YARN-1051:
----------------------------------------
Thanks Carlo and Subru for sharing the TR and design-doc.
Can you please verify my understanding is right (haven't read the TR yet, just
the design doc): The {{Admission Control}} box (Planning agent and Inventory)
takes care of figuring out if a reservation is feasible and managing the
corresponding inventory. Plan Follower would take care of actually submitting
the applications to the RM (scheduler) and scheduler-queue configurations come
show time; the updated scheduler-queue configurations would ensure these apps
would actually get the resources they need.
> 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.
