> Add GPU as a resource type for scheduling
> -----------------------------------------

> Key: YARN-5517
> URL: https://issues.apache.org/jira/browse/YARN-5517
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: scheduler
> Reporter: Jaeboo Jeong
> Attachments: RM-scheduler_metrics.jpg, YARN-5517-branch-2.7.1.patch,

>
> Currently YARN only support scheduling based on memory and cpu.
> There is the issue(YARN-3926) which proposed to extend the YARN resource
> model.
> And there is the issue(YARN-4122) to add support for GPU as a resource using
> docker.
> But these issues didn’t release yet so I just added GPU resource type like
> memory and cpu.
> I don’t consider GPU isolation like YARN-4122.
> The properties for GPU resource type is similar to cpu core.
