Thomas Graves commented on SPARK-27024:
---------------------------------------
This and SPARK-27005 basically split the design of the entire feature into 2.
The intention is for SPARK-27005 to be the core scheduler pieces and this one
is for the cluster manager and part of executor sides.
I will try to clarify the description when I get a chance to look at it a bit
more, probably early next week.
> Design executor interface to support GPU resources
> --------------------------------------------------
>
> Key: SPARK-27024
> URL: https://issues.apache.org/jira/browse/SPARK-27024
> Project: Spark
> Issue Type: Task
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: Xingbo Jiang
> Priority: Major
>
> The executor interface shall deal with the resources allocated to the
> executor by cluster managers(Standalone, YARN, Kubernetes), so the Spark
> Executor don’t need to involve into the GPU discovery and allocation, which
> shall be handled by cluster managers. However, an executor need to sync with
> the driver to expose available resources to support task scheduling.
