GroupStep.GroupBiOperator has serialization issues with Groovy lambdas. This is rectified by simply saying -- if the valueTraversal can not be serialized, then revert back to 3.2.0 behavior and simply propagate traverser sets instead of doing lazy barrier reductions when sets grow. Added a test to HadoopGremlinPluginCheck that verifies that both Spark and Giraph are happy. Also, updated a HadoopGremlinPluginCheck to ensure that non-sugar remote connections don't allow sugar (random side thing I noticed). CTR.
