The tests don't require spark. You just need to run the integration tests.
with docker it's as easy as: `docker/build.sh -t -i`. in a local maven
environment, you can `mvn verify -pl spark-gremlin
-DskipIntegrationTests=false` after a local build. I don't know spark-gremlin
too well, so i may have to dig into the testing stuff a bit to give you an
answer on the "graph test data" issue. i'll don't think i can get to that
today....not sure if anyone else can chime in with an answer.
