Suffering the same issue. Building the refresh neptune_python_utils.zip via the build.sh, glue etl job failed on the module tornado not found.

The build script should pin the gremlinpython to certain version or explicitly installing the tornado.

I think we need to pin gremlin-python to < 3.5.0 at the moment until Neptune supports 3.5.0. I'll look into doing that.
