["Konstantinos Karanasos (JIRA)" <ji...@apache.org>]

Konstantinos Karanasos reopened YARN-5468:
------------------------------------------

Based on offline discussions with [~leftnoteasy], [~asuresh] and [~subru], we agreed that there differences with YARN-4902, so I am reopening this JIRA.
We will use common APIs to specify constraints (either in the ResourceRequest or the ApplicationSubmissionContext).

> 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.
