----------------------------------
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.
