> When submitting application to Yarn and user don't specify any node-label on

> Yarn cluster in our internal company exists on-premise NodeManagers and
> elastic NodeManagers (which is built on K8s). To prevent application
> instability due to elastic NM decommission, we hope that the AM of job can be
> allocated to on-premise NMs.
