goblin.exception.GremlinServerError: 500: The provided key/value array length must be a multiple of two about goblin HOT 5 CLOSED

Hi Leif,
thank you for your quick reply.

I'm using TP 3.0.1, thought it was the latest one because of it's the latest version on Titan's website, where I got it from ( titan-1.0.0-hadoop1.zip ). I'm completely new on this, what setup would you recommend?

Kind regards,

Hi Francisco,

Thanks for your interest in Goblin, If you want to use Titan, I would suggest using Titan 1.1, but you will have to build it from the source contained in the Github repo, instructions for doing so can be found here: https://github.com/thinkaurelius/titan/blob/titan11/titan-dist/README.md.

However, depending on your use case, I would also recommend checking out DataStax Enterprise Graph, which looks to be the next big thing in distributed graph computing.

Best,

Hi Francisco, thanks for your feedback! Are you using TinkerPop 3.0? I've just been looking into this and it seems that a new API was added for the addV step in tp3.1, but that the old one is still supported.

The new API is the one of the form g.addV('developer').property('name', 'Leif'), while the old one has an even number of parameters because the label and any other properties are all defined as parameters on the addV step, like this: g.addV(T.label, 'developer', 'name', 'Leif'). If you're using TinkerPop 3.0 you will need to use the older API in raw gremlin queries; and I think we can patch the OGM so that vertices can be added with tp3.0.

Thanks again!

Thank you so much, happy days!

May I ask what would be right place to ask general questions about goblin?
