> 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*
