I agree that SPARK_VERSION does not seem to be used in these dockerfiles.
It was used in the [original
scripts](https://github.com/amplab/docker-scripts/search?q=SPARK_VERSION&ref=cmdform&type=Code)
I drew these from, but we don't actually rely on it.
I think we can just remove SPARK_VERSION here so we don't have to think
about maintaining it in the future.
