--------------------------------------
Summary: Support automatic spark.authenticate secret in Kubernetes
backend
Key: SPARK-26194
URL: https://issues.apache.org/jira/browse/SPARK-26194
Project: Spark
Issue Type: Improvement
Components: Kubernetes
Affects Versions: 3.0.0
Reporter: Marcelo Vanzin
Currently k8s inherits the default behavior for {{spark.authenticate}}, which
is that the user must provide an auth secret.
k8s doesn't have that requirement and could instead generate its own unique
per-app secret, and propagate it to executors.
