             Summary: Add an interface for device plugin to provide customized scheduler
                 Key: YARN-9015
                 URL: https://issues.apache.org/jira/browse/YARN-9015
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Zhankun Tang
            Assignee: Zhankun Tang


A vendor might need a customized scheduling policy for their devices. It could be scheduled based on topology, resource utilization, virtualization, device attribute and so on.

We'll provide another optional interface "DevicePluginScheduler" for the vendor device plugin to implement. Once it's implemented, the framework will prefer it to the default scheduler.

This would bring more flexibility to the framework's scheduling mechanism.
