Junfan Zhang updated YARN-11084:
--------------------------------
Description:
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.
> Introduce new config to specify AM default node-label when not specified
