Gremlin console and Titan custom attribute serializers - possible?

[sheshadr...@getfreebird.com]

Is there a trick to making gremlin console load custom attribute serializers ?  I'm using the 

attributes.custom.attribute1.attribute-class = java.util.HashMap

attributes.custom.attribute1.serializer-class = com.freebird.titan.serializer.MapSerializerScala

in properties file and when I open using TitanFactory, in gremlin console, I keep getting the error: 

Need to set configuration value: root.attributes.custom.attribute-class

When I try same properties file via Gremlin Server, I don't get any errors.

What am I doing wrong?

Thanks,

This example works fine https://github.com/pluradj/titan-attribute-serializer

Could you post the full configuration file?

Hi Jason,

Thanks for reply -- got consumed with other stuff... Here is the file contents (comments stripped out):

storage.backend=cassandra

storage.hostname=192.168.41.185,192.168.41.18

attributes.custom.attribute1.attribute-class = java.util.HashMap

attributes.custom.attribute1.serializer-class = com.freebird.titan.serializer.MapSerializerScala

attributes.custom.attribute2.attribute-class = org.joda.time.DateTime

attributes.custom.attribute2.serializer-class = com.freebird.titan.serializer.DateTimeSerializer

attributes.custom.attribute3.attribute-class = org.joda.time.LocalDate

attributes.custom.attribute3.serializer-class = com.freebird.titan.serializer.LocalDateSerializer

cache.db-cache = true

cache.db-cache-size = 0.25

index.search.backend=elasticsearch

index.search.hostname=192.168.41.18

index.search.elasticsearch.client-only=true

Was it clear that this exact configuration works with gremlin-server but doesn't work with gremlin-console (gremlin.sh). ?

Thanks,

oops -- forgot to mention that this is from titan-titan11 branch which I believe is Titan-1.0-SNAPSHOT (we have to use this 'cause that is the version that works with gremlin-scala).

Bump -- anyone ?

Did you put all of your serializer classes into $TITAN_HOME/lib/ directory? If you didn't package your classes as an uber jar, maybe you're missing some dependencies (like for joda or scala).

@location - yup

@package - yes i think so... it does work with the gremlin-server.  And gremlin console isn't complaining about any other missing classes except for the serializer - can't imagine that jvm would report an incorrect class loader error.

As far as you know if it should work in the gremlin console if it is working in gremlin server - correct?

BTW: Thanks for the reply.

Right, as I mentioned before, my example on GitHub works fine on both Gremlin Console and Gremlin Server.

Are you using the same properties file for both?

Hi Jason

Just wanted to thank you for the GitHub project illustrating the use of custom attributes. I created my own Serializer for ArrayList and LinkedHashMap using your example and got things working on JanusGraph as well.
