Hey, We have a mid-sized (10 million vertices, 5 billion edges) graph database (currently running on neo4j) at our organization. we are in the process of moving to JanusGraph with google cloud big table as the storage backend.

I am facing the following issue while connection to Big Table from the gremlin shell. I receive the following error while I try to instantiate the graph.

Jetty ALPN/NPN has not been properly configured.

Here is the traceback.

## Google cloud BIGTABLE configuration options
storage.hbase.ext.hbase.client.connection.impl=com.google.cloud.bigtable.hbase1_0.BigtableConnection
storage.hbase.ext.google.bigtable.project.id=my-project-id

cache.db-cache = true
cache.db-cache-clean-wait = 20

cache.db-cache-size = 0.5

I have added the google-cloud-bigtable and
netty-tcnative-boringssl-static jar files to the lib folder in janusgraph directory.

How I am trying to instantiate the graph

./bin/gremlin.sh
graph = JanusGraphFactory.open('conf/testconf.properties')

And this gives me the above error. Is there something that I am missing ?

NOTE

Also, when I run the gremlin-server I get the following warning message:

807  [main] WARN  org.apache.tinkerpop.gremlin.server.GremlinServer  - Graph [graph] configured at [conf/testconf.properties] could not be instantiated and will not be available in Gremlin Server.  GraphFactory message: Configuration must contain a valid 'gremlin.graph' setting

Looks like you've also filed a GitHub issue on this: https://github.com/JanusGraph/janusgraph/issues/450 — please use either the mailing list or GitHub to report issues, but not both, as duplication isn't helpful.

Since this might be a bug, let's follow up on GitHub.

Hi Misha,

Yes, I did, I am sorry. I have found the solution to this. Am going to post it and close the issue on github once I reach home. Sorry about the duplicate issue.
