Please have a look and let me know what you think. This at least would enable to set it up via spark operator, but I can open a different PR if you want that I modify the code to manage that env variable in the scala side as a managed option for 2.4. In 3.0 it can be handled via pod templates, have not tested it, but I think all scala is doing append variables, so defining that variable in a template could enable it ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
