Hi Raj, Do you need Janusgraph's OLAP part? If not, you might probably succeed in your scala 2.11 project if you simply exclude tinkerpop spark-gremlin from your janusgraph dependency. Note, I did

Re: Scala 2.10 vs. 2.11 build of Janus?

You say it would take some work. Do you have a ballpark estimate my customer can use for planning? Presumably, when Tinkerpop 3.3 snapshots get to "candidate" stage, you start tooling for them. After

Re: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are availa

Sounds like ES is not started or cannot connect. Are you using `bin/janusgraph.sh start` or do you have a standalone ES deployed? I'd suggest double checking the IP and port that ES is listening on,

Re: TimedOutException

cqlsh communicates using CQL interface, but JanusGraph uses Thrift. I'd suggest double checking that the RPC settings (rpc_address, rpc_port) in cassandra.yaml match what you have in

Re: Production Readyness
