[0.3.1] Remote graph not working by default

[darwinyip]

Running gremlin-server.sh and gremlin.sh leaving all default settings from the release archive does not work when trying to connect with remote graph.

> ./bin/gremlin.sh
gremlin> cluster = Cluster.open()
==>localhost/127.0.0.1:8182
gremlin> client = cluster.connect()
==>org.apache.tinkerpop.gremlin.driver.Client$ClusteredClient@242b6e1a
gremlin> aliased = client.alias("g")
==>org.apache.tinkerpop.gremlin.driver.Client$AliasClusteredClient@6f94fb9d
gremlin> g = org.apache.tinkerpop.gremlin.structure.util.empty.EmptyGraph.instance().traversal()
==>graphtraversalsource[emptygraph[empty], standard]
gremlin> aliased.submit(g.V())
org.apache.tinkerpop.gremlin.driver.exception.ResponseException: The traversal source [g] for alias [g] is not configured on the server.

Hey @darwinyip,

Firstly, I should say, you need to share gremlin-server logs for understand whats happening.

But in my option maybe your gremlin groovy scripts doesn’t work correctly because of your storage-backend or storage-index-backend doesnt work properly or working different ports and doesnt match janusgraph default ports.

First you need to check them and your gremlin server run at 8182.

Janusgraph using ‘elasticsearch’ as index backend and ‘cql’ storage backend with its default configuration. In this reason you should up elasticsearch before running your gremlin-server. If you use the run elasticsearch under janusgraph-0.3.1 release file, elasticsearch up at localhost:9200 (as default elasticsearch server).

jansugraph-cql-es-server.properties:

gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=cql
storage.hostname=127.0.0.1
storage.cql.keyspace=janusgraph
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.25
index.search.backend=elasticsearch
index.search.hostname=127.0.0.1:9200
index.search.elasticsearch.client-only=true

I tested it with default 'janusgraph-berkeleyje-es-server.properties' and i get an error. Maybe default configuration should be update for berkeleyje-es.properties

I change this:
index.search.hostname=elasticsearch
To:
index.search.hostname=127.0.0.1:9200

Then i follow your steps and get remote connection without errors.
