Subject [jira] [Commented] (YARN-5468) Scheduling of long-running applications

Konstantinos Karanasos commented on YARN-5468:
----------------------------------------------

Hi [~leftnoteasy],
I will post the patch in YARN-4902, as you suggest. 
Albeit overlapping, I do not think this JIRA is a duplicate. Probably it looks like so, given
the very initial version of the patch.
But let's continue the discussion in the other JIRA to reach consensus.

> This JIRA is about the scheduling of applications with long-running tasks.
> It will include adding support to the YARN for a richer set of scheduling constraints
(such as affinity, anti-affinity, cardinality and time constraints), and extending the schedulers
to take them into account during placement of containers to nodes.
> We plan to have both an online version that will accommodate such requests as they arrive,
as well as a Long-running Application Planner that will make more global decisions by considering
multiple applications at once.
