------------------------------
Summary: CLONE - Add configurable auth secret source in k8s backend
Key: SPARK-26522
URL: https://issues.apache.org/jira/browse/SPARK-26522
Project: Spark
Issue Type: New Feature
Components: Kubernetes
Affects Versions: 3.0.0
Reporter: Euijun
Assignee: Matt Cheah
Fix For: 3.0.0
This is a follow up to SPARK-26194, which aims to add auto-generated secrets
similar to the YARN backend.
There's a desire to support different ways to generate and propagate these auth
secrets (e.g. using things like Vault). Need to investigate:
- exposing configuration to support that
- changing SecurityManager so that it can delegate some of the secret-handling
logic to custom implementations
- figuring out whether this can also be used in client-mode, where the driver
is not created by the k8s backend in Spark.
