Hi folks, I am new to JanusGraph. When I look at the tutorials it is all about the query language - how to query and traverse the graph. I can find very little on how to create vertices, edges,

Can the graph.set-vertex-id setting be changed

For the configuration setting graph.set-vertex-id, the documentation says: Whether user provided vertex ids should be enabled and JanusGraph’s automatic id allocation be disabled. Useful when

Re: Getting illegal access error due to unsupported GoogleGuava 21?

Yup. this is the famous Guava (or infamous?) compatibility issue. JanusGraph server is a good solution. Or you will need to find a way to shade your version of Guava. Unfortunately, JanusGraph does

Re: Getting illegal access error due to unsupported GoogleGuava 21?

Hello Robert, I have never used the JanusGraph server; as such I am not sure if we can write complex programs and save them for later use and integration - my code currently sits in between two code

Re: Hardware Calculation

The short answer is no.. Number of instances depends on the workload you will be running on the Janusgraph. You need to design your workload, test it on your Janusgraph instance with desired usage

Re: Getting illegal access error due to unsupported GoogleGuava 21?

Using the JanusGraph (Gremlin) Server will help decouple your dependencies. See also http://docs.janusgraph.org/latest/server.html Robert Dale

Thank you Marc. I did not set spark.executor.instances, but I do have spark.cores.max set to 64 and within YARN, it is configured to allow has much RAM/cores for our 5 server cluster.

Hardware Calculation

Hi everyone, Is there some hardware calculator available for janusgraph to calculate how many instances of janus and cassandra would we require. Any help will be much appreciated. -- Thanks &

Re: [BLOG] Configuring JanusGraph for spark-yarn

Hi Joe, Another thing to try (only tested on Tinkerpop, not on JanusGraph): create the traversalsource as follows: g = graph.traversal().withComputer(new

Creating a mixed index on an existing graph

I'm trying to add a mixed index with one key to an existing graph. After building the index, I do a commit on the JanusGraphManagement, and then awaitGraphIndexStatus(graph, mykey).call(). The

Re: [BLOG] Configuring JanusGraph for spark-yarn

Marc - thank you. I've updated the classpath and removed nearly all of the CDH jars; had to keep chimera and some of the HBase libs in there. Apart from those and all the jars in lib.zip,

Re: [BLOG] Configuring JanusGraph for spark-yarn

Hi Gari and Joe, Glad to see you testing the recipes for MapR and Cloudera respectively! I am sure that you realized by now that getting this to work is like walking through a minefield. If you

Re: [BLOG] Configuring JanusGraph for spark-yarn

Hi Marc - I did try splitting regions. What happens when I run the SparkGraphComputer job, is that it seems to hit one region server hard, then moves onto the next; appears to run serially.

How can we bulk load the edges while we have the vertexes in our JanusGraph DB?

Assume, we have the vertexes in DB. and we have the edge information in GraphSON/XML/TXT? how can we import the edges into JanusGraph?

Vertex ID data type

Currently JanusGraph vertex ID is of type 64bits long, is it possible to also support UUID as the vertex ID?

Re: [BLOG] Configuring JanusGraph for spark-yarn

Could you let us know a little more about your configuration? What is your storage backend for JanusGraph (HBase/Cassandra)? I actually do not see an error in your log, but at the very
