Turns out that I needed to set the java.io.tmpdir somewhere other than /tmp (assuming that's the default).  Not sure why exactly, but by setting JAVA_OPTIONS

Getting this error when trying to run Gremlin on an AWS EC2 instance - exactly

When I run the following code with janusgraph-inmemory and janusgraph-lucene both in version 0.6.2. PropertiesConfiguration conf =

Thanks Marc for the Quick Update.

Unfortunately, JanusGraph does not support basic authentication on its SOLR client yet, see https://github.com/JanusGraph/janusgraph/issues/1056 Before finding this JanusGraph issue, I came across

Hello Everyone, iam trying to index dynamic graphs with solr index,but iam facing below error. ############################################# gremlin> sg.V().has('state',

I agree. If you start out with an empty graph, the Lucene index is not created until you add the first vertex. It is not easy to find why Lucene would only allow alphanumeric characters for names of

Hey everyone,I'm currently running janusgraph-inmemory with janusgraph-lucence both version 0.6.2 And I'm experiencing strange behaviour when creating an index that contains an underscore in its

Are you sure the JanusGraph hadoop-2.x clients cannot be used with your hadoop-3.x cluster? See: https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/Compatibility.html#Policy Marc

Thanks for response Mark. Yes i am using JanusGraph as input to SparkGraphComputer. We had Hadoop3 which is not supported in tinkerpop 3.5 but as per documentation its supported by Tinkerpop 3.6, so

Hi Anjani, Does hdfs work from the Gremlin Console? See the example

Saw the same thing awhile back. Boxuan put in a Jira for it: https://github.com/JanusGraph/janusgraph/issues/2966

Hi Marc - yes, it takes minutes to do queries on nodes with lots of edges. Like: :> g.V().has("somevar","someVal").outE().has("indexedField","value") I believe this is because of

Hi All, I am running SparkGraphComputer using tinker-pop library on Yarn. I am able to run vertex program successfully and write final output to a mount location. But I a want to make program to write

Hi Joe, You do not describe whether breaking this rule of thumb causes real performance issues in your case. Anyway, JanusGraph allows you to partition the stored edges of a node, see:

I've noticed that the max partition size on Cassandra can get extremely large if you have a node with lots of edges.  The max partition size on the edgestore table on a graph I'm working on is over

Thank you Kevin and Boxuan for the help on this. I was scratching my head on this and decided to blow away the graph and try again. Every-time, I built a small graph and exported to

Hi Joe, > The java code talks directly to cassandra via the Janusgraph library. Should I be using a Gremlin server instead? I see, so you are using embedded JanusGraph. It has less overhead compared

Hi Joe, I just wanted to check a few things: 1. Did you happen to enable `storage.batch-loading`? See https://docs.janusgraph.org/operations/bulk-loading/#batch-loading 2. IIRC you are using

Joe, See https://groups.google.com/g/janusgraph-users/c/foaqfG-MB5E/m/tsNnkhPtBwAJ for a discussion on perhaps the same issue you are running into. Long story short, it appears you have a unique
