Getting an error when running simple Gremlin script in Faunus

[levin-royl]

I am using titan-all version 0.4.4

Code:

    Configuration config = GraphUtil.readGraphConfigFromFile("titandb-faunus-remote.properties");

    FaunusGraph g = new FaunusGraph(FaunusUtil.toHadoopConfig(config));

    FaunusPipeline pipe = new FaunusPipeline(g);
    pipe.V().groupCount(ElementKeySchema.typeToken);
    pipe.submit();

Config File:

Looks like the groupCount closure is causing the error. Where does ElementKeySchema.typeToken come from?

[levin-royl]

Thanks for your response, I thought of that and even removed the groupby altogether (i.e., running no query at all) but still I get the same error. Seems to me like there is some conflict with jar versions but I can't find out what's causing it ...

[dkuppitz]

The stacktrace contains:

at com.thinkaurelius.faunus.FaunusPipeline.validateClosure(FaunusPipeline.java:1096)
at com.thinkaurelius.faunus.FaunusPipeline.groupCount(FaunusPipeline.java:939)
at com.thinkaurelius.faunus.FaunusPipeline.groupCount(FaunusPipeline.java:925)

Not sure how you're able to get the same error if you remove the groupCount step. Please try to use a very basic query, like:

new FaunusPipeline(g).V().count().submit();

[levin-royl]

I meant similar error. Here is what I get using the count query you suggested:

FYI--- the code is running from my local machine (in eclipse) and the graph is stored in a remove server running hbase.

@levin-royl Which version of ASM is on the runtime classpath when the latest exception you pasted is thrown?

[dkuppitz]

Maybe this discussion on the mailing list can help. Seems like some people ran into the same - or at least into a related - issue.
