I tested out the Neo4j HA configuration with TinkerPop yesterday and it worked nicely. We sometimes get questions about how to set that up or how to get Gremlin Server to point at a cluster rather than run in embedded mode, so it was nice to see this working. I wrote up some documentation on how to get this configured in TinkerPop:
http://tinkerpop.apache.org/docs/3.2.1-SNAPSHOT/reference/#_high_availability_configuration It's pretty simple really. TinkerPop really just acts as a pass through for Neo4j configuration options so if you follow Neo4j's instructions in their documentation you just append those options into your TinkerPop graph instances and you should be good to go. I was able to get a three node cluster running purely in Gremlin Server going in just a few minutes. Note that while I referenced 3.2.1 documentation above, this feature should work in both 3.1.2-incubating (maybe all of 3.1.x but i didn't test) and 3.2.0-incubating.
