> Add configurable auth secret source in k8s backend
> --------------------------------------------------

>                 Key: SPARK-26239
>                 URL: https://issues.apache.org/jira/browse/SPARK-26239
>             Project: Spark
>          Issue Type: New Feature
>          Components: Kubernetes
>    Affects Versions: 3.0.0
>            Reporter: Marcelo Vanzin
>            Priority: Major
>
> 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.
