> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 3.4.1
> Reporter: Qian Sun
> Assignee: Apache Spark
> Priority: Minor
> Labels: pull-request-available
>
> krb5.conf currently only supports the local file format. Tenants would like
> to save this file on their own servers and download it during the
> spark-submit phase for better implementation of multi-tenant scenarios. The
> proposed solution is to use the *downloadFile* function[1], similar to the
> configuration of *spark.kubernetes.driver/executor.podTemplateFile*
>
