Jonathan Hung commented on YARN-9760:
-------------------------------------
Hi [~eepayne], thanks for the comments. I understand the concern. The reason we
implemented it this way was b/c we wanted queue admins to be able to set
workflow priorities themselves (i.e. leveraging YARN queue ACLs) which would be
difficult to do client-side.
IMO there's not too much complexity for this feature on the RM side. But to
minimize overall complexity, perhaps we can do this in a way that doesn't make
protocol changes, and on the RM side we can leverage the queue mapping
interface. Would this address your concerns? [~varun_saxena] how does this
sound?

> Currently priorities are submitted on an application level, but for end users
> it's common to submit workloads to YARN at a workflow level. This jira
> proposes a feature to store workflow id + priority mappings on RM (similar to
> queue mappings). If app is submitted with a certain workflow id (as set in
> application submission context) RM will override this app's priority with the
> one defined in the mapping.
