> Spark on K8s allows to place driver/executor pods on specific k8s nodes, using nodeSelector.
NodeSelector is a very simple way to constrain pods to nodes with particular labels. The [affinity/anti-affinity|https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity]
feature, currently in beta, greatly expands the types of constraints you can express. Aim
here is to bring support of this feature to Spark on K8s, in detail:
>  * Node affinity
>  * Toleration/taints
>  * Inter-Pod affinity/anti-affinity
> Note that nodeSelector will be deprecated in the future.
> Design doc: [https://docs.google.com/document/d/1izk75I4A0I-nJaE57m7wkpgUZTXM0o6-c0Tb-NxdOMU|https://docs.google.com/document/d/1izk75I4A0I-nJaE57m7wkpgUZTXM0o6-c0Tb-NxdOMU/edit?usp=sharing]
