[jira] [Created] (TINKERPOP-1358) spark-gremlin tests require special setup

Robert Dale created TINKERPOP-1358:
--------------------------------------

             Summary: spark-gremlin tests require special setup
                 Key: TINKERPOP-1358
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1358
             Project: TinkerPop
          Issue Type: Test
          Components: hadoop
    Affects Versions: 3.2.0-incubating
         Environment: Linux
No spark, hadoop installed, configured, or running.
No spark, hadoop env vars set.
            Reporter: Robert Dale
             Fix For: 3.2.1


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.
