I just tested it locally and works well and the size has been reduced drastically :). I haven't tested it out but just wanted to be sure that we will not exclude [submit](https://github.com/big-data-europe/docker-spark/tree/master/submit) and [templates](https://github.com/big-data-europe/docker-spark/tree/master/template) ([java](https://github.com/big-data-europe/docker-spark/tree/master/template/java), [python](https://github.com/big-data-europe/docker-spark/tree/master/template/python), [scala](https://github.com/big-data-europe/docker-spark/tree/master/template/scala)) images while we remove the installation of mvn, python, sbt from the base image. I know that we do install them on the template image (e.g. https://github.com/big-data-europe/docker-spark/blob/master/template/java/Dockerfile#L11 ) but would be good if we can test it.\r\n\r\nDid you have a chance to test the templates images? I just tested it from the spark-shell and works. If that works as well, I'm okay to merge it. \r\n\r\nBest regards,"}}
