OK, I repeated the experiment and got "0 1" again, so I expand on what I did. I use the janusgraph-0.6.2 full binary distribution and start cassandra and elasticsearch with: $ bin/janusgraph.sh start

Thanks for bringing this up. Indeed, managing custom images is a barrier that you sometimes want to avoid. Can you give the runtime configuration of the standard image a try and report back where this

Hi inverseintegral, You have been quite succesful as a test driver, that is detecting easily reproducible issues! The current issue seems more like an issue of undefined behaviour, rather than an issu

I assume you reposted this inadvertenly? I saw you created issue https://github.com/JanusGraph/janusgraph/issues/3146 to document this inconvenience. Thanks, Marc

OK, good catch, it is a bug. I had not recognized Long.MAX_VALUE in your query. The LuceneIndex class converts the neq to a range query and adds + 1 to the requested value without any check. The write

I am not sure what the trouble is in your approach. Using variable names key and label might be problematic (it is in the Gremlin Console). Rather than building out your example, I chose to rework the

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 the

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 i

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

Hi Anjani, Does hdfs work from the Gremlin Console? See the example at: https://tinkerpop.apache.org/docs/current/reference/#_installing_hadoop_gremlin https://tinkerpop.apache.org/docs/current/refere

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: https://docs.ja

Hi Joe, Do you mean with threadsafe transactions that requests from different client threads should be handled independently, that is in different JanusGraph Transactions? In that case, I think you wa

Great stuff! Is is really motivating to gain a much deeper understanding of the JanusGraph inner workings and get practical advice at the same time. Marc

Hi Nikita, Do you use the spark web UI? In the executor tab you can follow the stderr link and see any logged or printed output. No idea why they use stderr. Best wishes, Marc

Hi Senthilkumar, I remember the Gremlin.version() output of 1.2.1 in the gremlin console of the janusgraph distribution is a bug somewhere. You can look in the lib folder and see that janusgraph-0.6.1

Hi Senthilkumar, Sounds like the "getting started deployment scenario", see https://docs.janusgraph.org/operations/deployment/#getting-started-scenario JanusGraph servers only need to have the exact s

Hi Nikita, JanusGraph can be run as a server or in embedded mode. gremlin-server.yaml is for configuring JanusGraph Server. With JanusGraphFactory in the Gremlin Console you instantiate embedded Janus

Hi Nikita, Possibly, your previous setup included JanusGraph Server and you had a remote connection from the Gremlin Console to JanusGraph Server. In that case, succesful gremlin requests are committe

Hi Nikita, Sorry for asking the obvious, but are you sure you committed the addV() transaction with a g2.tx().commit() before closing the Gremlin Console? Best wishes, Marc

Hi Joe, What is slow? Can you please check the Expero blog series and compare to their reference numbers (per parallel spark task): https://www.experoinc.com/post/janusgraph-nuts-and-bolts-part-1-writ
