[question]koordinator yarn跑实时流计算作业

[zj619]

如果用koordinator yarn跑实时流计算作业，怎么让流计算任务不被驱逐。目前观察到nm的pod里面有个koordinator.sh/qosClass: BE的配置，另一个是slo-controller-config的host-application-config里面有个qos为BE的配置，这两种有什么区别，怎样做才能满足koordinator yarn跑实时流计算作业不被驱逐？

如开源例会讨论，YANR stream/batch混在一起和k8s混部，这种是不支持的；YARN stream单独和K8s部署不建议通过混部模式。
