Lujila,
This would be better addressed in the JanusGraph users list. https://groups.google.com/forum/#!forum/janusgraph-users
This issue can happen if you don't have elasticsearch running/configured properly. Try just running `graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje.properties')`
You also shouldn't need to sudo to run JanusGraph. just run bin/gremlin.sh, though it may cause issues for you now if you don't since the BerkeleyDB directory was created with sudo privileges.
Cheers,
Keith
