Stavros Kontopoulos updated SPARK-24353:
----------------------------------------
Description:
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
* Pod affinity/anti-affinity
Selecting where to run drivers and executors covers many cases like the ones
described here:
Note that nodeSelector will be deprecated in the future.
