Hi Hemi, Glad to hear that your problem is solved! As for deploying a flink cluster, you can check these docs for more information based on your resource provider: YARN: https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/resource-providers/yarn/ K8s: https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/resource-providers/native_kubernetes/ If you are using k8s and are more familiar with kubectl, it is worthwhile to mention that you can have a try on flink k8s operator: https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/zh/docs/try-flink-kubernetes-operator/quick-start/
