Lei Guo commented on YARN-5468:
-------------------------------

[~kkaranasos], do we have a design document? I'd like to get more details regarding the difference between this Jira and Yarn-4902, and whether there will be some feature interaction between these two features.

> 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.
