Hello, We will be hosting a community meetup next week on Tuesday, May 18th at 9:30 central/10:30 eastern. We have a great set of speakers who will be discussing all things JanusGraph OLAP: * Hadoop

Hi Marc, you are right, we are indeed using this -files option :)

Hi Boxuan, Using existing mechanisms for configuring mapreduce would be nicer, indeed. Upon reading this hadoop command, I see a GENERIC_OPTIONS env variable read by the mapreduce client, that can

We have been using a yarn cluster to run MapReduce reindexing (Cassandra + Elasticsearch) for a long time. Recently, we introduced Kerberos-based authentication to the Elasticsearch cluster, meaning

Hello, I encounter the error describe in the issue #1916 (https://github.com/JanusGraph/janusgraph/issues/1916) on a mixed index (lucene). When I list property keys of the index, they are all

Hi Marc, Thanks for the reply. Yeah, it's true that a multi-node setup uses the same storage backend. However, I am referring to here is the Janusgraph database cache -

Hi All, I am using connected component vertex program to find all the connected nodes in graph and then using that RDD for further processing in graph. I want to store that RDD at some output location

Thanks for help Marc, i will try updating value of ids.num-partitions = number of executors.

Hi Anjani, It is a while ago I did this myself. I interpret ids.num-partitions as a stock of reserved id blocks that can be delegated to a janugraph instance. It does not have a large value to not

We have 250 parallel spark task running for creating node/edges. I didn't get parallel tasks - (for setting ids.num-partitions)? Could you please help me on it?

What is the number of parallel tasks? (for setting ids.num-partitions) You have the ids.authority.wait-time still on its default value of 300 ms, so that seems worthwhile experimenting with. Best

Thanks for response Marc. Below is the method i am using to create janus connection: public JanusGraph createJanusConnection(HashMap<String, Object> janusConfig) { JanusGraphFactory.Builder

Hi Anjani, Please show the properties file you use to open janusgraph. I assume you also saw the other recommendations in

Hi All, I am creating vertex and edges in bulk and getting below error while creating edge. Below is the exception log:I tired increasing value of "ids.block-size" but still no luck, even set to 1B

Hi Vinayak, Actually, query 4 was easier to rework. It could read somewhat like: g.V().has('property1', 'vertex1').as('v1').outE().has('property1', 'edge1').limit(100).as('e').inV().has('property1',

Hi Marc, Thank you for your reply. I will try to report this issue on janusgraph repository. Regarding the work around you suggested, if possible please share the updated query with work around for

Hi Vinayak, If you would bother to demonstrate this behavior with a reproducible, generated graph, you can report it as an issue on github. For now, you can only look for workarounds: - combine the

Hi Marc, This query takes 18 sec to run by changing as to aggregate and select to project. But still, 99% of the time is taken to compute union. There is no memory issue, it already set to

Hi Vinayak, Your last remark explains it well: it seems that in JanusGraph a union of multiple clauses can take much longer than the sum of the individual clauses. There are still two things that we

Hi Marc, That works as expected. Union also works as expected as in Query1 but when I add limit to all edge the performance degrades. Thanks
