Thanks Debasish,

I haven't modified any configuration file. 
I'm just running the docker image as is from the image repository as I indicated.

I tried the following as you suggested. Not sure if I'm doing it right: 

gremlin> graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje.properties').loadWithoutMixedIndex(true)

And still get this error:

11:15:02 WARN  org.janusgraph.diskstorage.es.rest.RestElasticSearchClient  - Unable to determine Elasticsearch server version. Default to FIVE.

Also if I look at the README in the docker repo and try to do the same it doesn't work.

https://hub.docker.com/r/janusgraph/janusgraph

docker run --rm --link janusgraph-default:janusgraph -e GREMLIN_REMOTE_HOSTS=janusgraph \

So it looks like something changed in Gremlin and wasn't propagated to the instructions everywhere.

Are you specifying the elastic search index connection properties in your berkey.properties file?

If you don't want to use ES and using this just for exploration purpose then you can use .loadWithoutMixedIndex(true). That should resolve your problem

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

Hi Team, so I'm new to JanusGraph and having trouble with following the getting started tutorial from JanusGraph website. 

First, when I open Gremlin Shell, it gives a lot of warnings, which is concerning. Also having issue with executing graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje-es.properties')

Error trace is long, if needed, I can post more error traces.

Please help.
