Connection refused when using janusgraph-berkeleyje-es.properties

[sarath...@gmail.com]

Hello,

I'm trying to follow the getting started JanusGraph with version 0.2.0 and downloaded the binary: janusgraph-0.2.0-hadoop2.zip

But when I tried to use the gremlin shell and connect using conf/janusgraph-berkeleyje-es.properties I get the below exception. 

I don't see this issue with JanusGraph 0.1.1 binaries and I'm able to connect using the same properties. Is there any additional configuration that needs to be set?

Thanks,

Sarath Subramanian

[Jason Plurad]

The conf/janusgraph-berkeleyje-es.properties uses ES local mode, which is no longer supported in JanusGraph 0.2.0. If you want to use Elasticsearch, you should start up a an Elasticsearch node. I've opened up an issue to track this.

If you're looking for a simple embedded option, janusgraph-berkeleyje-lucene.properties is good for that. Make sure you clear your storage.directory first (or use a different storage directory), otherwise it'll still have the old configuration for ES.

Thanks Jason! I will try the lucene option.
