> h2. What
> When submitting application to Yarn and user don't specify any node-label on AM request and {{{}ApplicationSubmissionContext{}}}, we hope that Yarn could provide the default AM node-label.
>  
> h2. Why
> 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.
