Wangda Tan updated YARN-8016:
-----------------------------
Description:
After YARN-3635/YARN-6689, PlacementRule becomes a common interface which can
be used by scheduler and can be dynamically updated by scheduler according to
configs. There're some other works.
- There's no way to initialize PlacementRule.
- No example of PlacementRule except the user-group mapping one.
This JIRA is targeted to refine PlacementRule interfaces and add another
PlacementRule example.
was:
Currently in Capacity Scheduler, we hard code queue mappings to
UserGroupMappingPlacementRule for queue mappings.
We need to expose a general framework to dynamically create various queue
mapping placement rules by reading queue mapping rule property from
capacity-scheduler.xml
> Refine PlacementRule interface and add a app-name queue mapping rule as an
> example
