Description

cd spark-gremlin; mvn clean install

Most tests fail with:
java.net.BindException: Cannot assign requested address: Service 'sparkDriver' failed after 16 retries!

Eventually leads to resource starvation: OutOfMemoryError: unable to create new native thread. Presumably because exceptions are not caught and SparkContexts closed.

If tests require external server, perhaps they would be best served as integration tests. Otherwise, there's some undocumented special sauce missing.
