             Summary: Support to set node selector for JM/TM pod 
                 Key: FLINK-16749
                 URL: https://issues.apache.org/jira/browse/FLINK-16749
             Project: Flink
          Issue Type: Sub-task
          Components: Deployment / Kubernetes
            Reporter: Yang Wang
             Fix For: 1.11.0


The [node-selector|https://kubernetes.io/docs/concepts/configuration/assign-pod-node/] is a collection of key/value pairs to constrain a pod to only be able to run on particular node(s). Since affinity and anti-affinity are uncommon use case for Flink, so we leave the support in pod template.
