-------------------------------------------
Summary: Add support for pod affinity/anti-affinity
Key: SPARK-24353
URL: https://issues.apache.org/jira/browse/SPARK-24353
Project: Spark
Issue Type: New Feature
Components: Kubernetes
Affects Versions: 2.3.0
Reporter: Stavros Kontopoulos
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 to Spark on K8s. Note here that
nodeSelector will be deprecated in the future.
