The 2.6.0 stil compatible with titan 0.4.4 ?

[Stephen Mallette]

Titan 0.4 is only compatible with TinkerPop 2.4.0.  You will find TinkerPop 2.5.0 bound to Titan 0.5.  There is no official support for Titan under TinkerPop 2.6.0 yet.  Unofficially speaking, it wouldn't surprise me if it Titan 0.5 could work with TinkerPop 2.6.0 if you could get all the dependencies right.

I just answered a different question in the aurelius graphs mailing list that I think nulls out my thought regarding things "unofficial" working.  I'm not so sure it will anymore as we added a new field to the Feature class to better help some of the vendors with their implementations.  Titan would need to expose that field to be compliant, so my new guess is that it won't work until that happens.

Hello Stephen,

Thank you for your answer

I'm realy bad in english so I'm not sure I realy enderstend what you mine in the second message.

I was using titan 0.4.4 with thinkerpop 2.5 (and scala gremlin) with no problem else than index problem. So when I seen scala gremlin update for index I decided to follow and update to thinkerpop 2.6.0.

So know i have two solution, try to import my sefl the missing dependency or upgrade to titan 0.5 (which seems not stable) and prey for compatibility.

[Stephen Mallette]

You are mixing these libraries without official compatibility support, so all I can say is to do this at your own risk.  The specific problem you are having regarding:

cern/colt/map/AbstractIntObjectMap]

is related to the fact that this dependency was removed from Blueprints 2.6.0.  It was replaced with:

http://labs.carrotsearch.com/hppc.html

I think that if you can resolve that problem things "might" work.  I'm just saying that Titan does not officially support this configuration.
