Im following this tutorial

http://s3.thinkaurelius.com/docs/titan/0.9.0-M1/server.html

from the gremlin.sh command line it connects fine :

gremlin> :remote connect tinkerpop.server conf/remote.yaml

==>Connected - localhost/127.0.0.1:8182

but when i try to add anything to the graph :

gremlin> :> g.addVertex('name','steve')

it throws this error:

WARN org.apache.tinkerpop.gremlin.driver.MessageSerializer - Response [UnpooledUnsafeDirectByteBuf(ridx: 136, widx: 136, cap: 136)] could not be deserialized by org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0.

WARN org.apache.tinkerpop.gremlin.driver.MessageSerializer - Response [UnpooledUnsafeDirectByteBuf(ridx: 102, widx: 102, cap: 102)] could not be deserialized by org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0.

Request timed out while processing - increase the timeout with the :remote command

and it either hangs or goes back to the gremlin console command line. I can't find much on this anywhere online, much help is apprecaited

thanks

I'm not sure how you got your version of Titan 0.9.0-M1, but I'm guessing that you have some discrepancy between versions somewhere. Did you download these two versions of M1:

http://s3.thinkaurelius.com/downloads/titan/titan-console-0.9.0-M1.zip
http://s3.thinkaurelius.com/downloads/titan/titan-server-0.9.0-M1.zip

I would expect them to work together. This first release in M1 was really early for Titan on the TP3 API and was meant for users already familiar with the stack. If you're new to Java coming from Ruby, learning graphs, learning TinkerPop, and then throwing early release Titan in the mix, you have much to digest. I always like to suggest that newcomers get comfortable with TinkerPop first (prior to getting too deep into Titan). TinkerGraph is a great way to just get everything running and have some early successes that you can feel good about. Anywho, just a suggestion....

Titan 0.9.0-M2 should be releasing soon which should have a better packaging structure than what we had in M1 (where console and server packaging were separate). I just built it a moment ago and it worked nicely with the documentation). Anyway, we're happy to help you along if you get stuck somewhere in your work. Please let us know if the downloads above don't resolve your issue or if you run into more trouble elsewhere.

thanks again Stephen.

i thought the latest was - 0.5.4 from here

https://github.com/thinkaurelius/titan/wiki/Downloads

and i had to patchwork things together. Titans tutorial says the gremlin-server is bundled with the latest Titan (5.4) but it wasn't so i went the painful manual way and ran into things along the way

Actually, i am coming from java to ROR, new job, new IDE, graph DB is new to my RDB mind and i went from Windows to Mac. FUN! but that is why we do this i suppose. right?

So, you are my savior and because of you i wont be standing in an unemployment line or applying for PHP jobs. Thanks!

To be sure I cleared up the versioning issue......

Titan 0.5.4 is the current "stable" version. It is based on on TinkerPop 2.x. You referenced that you were looking at this:

http://s3.thinkaurelius.com/docs/titan/0.9.0-M1/server.html

note that given that URL, those docs relate to Titan 0.9.0-M1. you want:

http://s3.thinkaurelius.com/docs/titan/0.5.4/

Further note, that if you want docs related to TinkerPop, given usage of Titan 0.5.4, you will need to look at the individual TinkerPop project wikis in github and not the http://tinkerpop.com website which is already outfitted for TinkerPop 3.x. Titan 0.9.0-M1 and future release in that line relate to the wholly redesigned TinkerPop 3.x, which has a whole new set of interfaces, features, etc.:

http://tinkerpop.incubator.apache.org/docs/3.0.0.M8-incubating/

TinkerPop 3.0.0.M8 is the current "official" release but we are currently working on 3.0.0.M9. And here's where the final bit of confusion lies: Titan 0.9.0-M1 uses TinkerPop 3.0.0.M6 (which is mighty old). Titan 0.9.0-M2 will rely on the latest and greatest TinkerPop 3.0.0.M9 when it releases in the coming week or so. If you build the titan09 branch from GitHub it currently works with an early release candidate of 3.0.0.M9.

Soooooo....short answer - versions matter and need to match up appropriately.

HTH,

Stephen
