@jlpedrosa I think the idiomatic way to do this (going forward) will be to:
1) specify java security modifications via a file, mounted as a configmap.
2) set the `-Djava.security.properties` via `--driver-java-options`
Config map support is slated to be supported via user supplied YAML, see:
https://issues.apache.org/jira/browse/SPARK-24434
This feature will land in 3.0, so I'd propose verifying that this can be done without new code starting with 3.0
