remotegraph - invalid opprocessor - with traversal()

[Cristian Tarsoaga]

Hi everyone,

I try to connect to titan via remotegraph and use traversal()

Graph graph = RemoteGraph.open(confFile); //ok
List<Vertex> vertices = graph.traversal().V().toList(); //server error

but the server returns a response exception

78881 [gremlin-server-worker-1] WARN  org.apache.tinkerpop.gremlin.server.handler.OpSelectorHandler  - Invalid OpProcessor requested [traversal]
org.apache.tinkerpop.gremlin.server.op.OpProcessorException: Invalid OpProcessor requested [traversal]
        at org.apache.tinkerpop.gremlin.server.handler.OpSelectorHandler.decode(OpSelectorHandler.java:84)

Debugging the server code, I noticed that the processor ('traversal') is not found in the processors list, which contains ""(standard op processor), "session" and "control" 

Any idea?

Thanks,

Chris

if you are on Titan 1.0, that won't work. RemoteGraph was recently introduced in 3.2.0 and titan 1.0 is still on the 3.0.x line. You would have to try out this PR:

https://github.com/thinkaurelius/titan/pull/1312

which is based on 3.2.0 if you wanted to test out RemoreGraph.

Indeed, I am using titan 1.0 (tinkerpop 3.0.1) so I guess that's the problem

thanks a lot!
