Hi Craig! Maven 3.3.x has a shading problem. You need to build two times, once from root, once inside "flink-dist". Have a look here:
https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/building.html#dependency-shading Maybe that way missed in BigTop? I am wondering if we should actually throw an error if building with Maven 3.3.x - too many users run into that issue.
