This will be mounted as an empty directory volume passed to the driver pod in plaintext otherwise. Here is how you would execute a Spark-Pi example: With Python support it is expected to distribute .egg, .zip and .py libraries to executors via the --py-files option. Although the docs of --archive don't mention executor, I tested and it's working. In order to use a volume, you should specify the volumes to provide for the Pod in .spec.volumes and declare where to mount those volumes into containers in .spec.containers[*].volumeMounts.
