use "gremlin-driver" Reported abnormal “ Timed out waiting for an available host ”

[okuc]

Hello everyone!

I follow the "http://s3.thinkaurelius.com/docs/titan/1.0.0/server.html" steps initiated titan service, and the use of "Gremlin Console" connection to run, it can run well.

But when I use the "gremlin-driver" to connect to it, reported the following error, who knows why? Thank you!

I use titan server is titan-1.0.0-hadoop2 comes, java code is as follows:

     Cluster cluster = Cluster.open (App.class.getClassLoader () getResource ("") getPath () +. "Com / abc / TestTinkerpop / remote.yaml".);
     Client client = cluster.connect ();
   
     ResultSet results = client.submit ("graph.addVertex ('name', 'stephen')");

If you can connect with the Gremlin Console and :remote then I would full expect for you to be able to use the same configuration file to connect with the driver.  I can only guess that:

> Cluster.open (App.class.getClassLoader () getResource ("") getPath () +. "Com / abc / TestTinkerpop / remote.yaml".);

isn't pointing at the file as you think it is?

I guarantee that this is the same profile.

I tracked here, no problem, you can find the configuration file.

Thank you！

Well - there is clearly some mis-configuration with the driver, but I don't see it from the information you've supplied. The :remote and :> commands use the driver internally to connect to Gremlin Server so I'm not sure how you could get into a state where one works and not the other unless there you really aren't using the configuration you think you are or some other environmental issue.  Perhaps you should simplify and validate that you can get the driver to connect from localhost...maybe that would give you some new clues.

I'll “gremlin-server-modern.yaml” profile host, from “host: localhost” change “host: 192.168.90.22”, it is normal, thank you!
