Hi all, is it possible run gremlin.sh in background? I try to use `-e` argument to run a groovy script, and always change to stopped status, but it can finish when change to in foreground. ``` [bin]$

Hello, I'm writing a Java program that, for various implementation details, needs to open the same graph multiple times. Currently I'm using JanusGraphFactory.open(...), but this always looks up the

Hi Marc, Thank you for your advice, I will try it and tell you result. Your advice is the trace of light in the dark, I so desire.

Hi Marc, Profile outputs I tried. 1. g.V().has('serial',within('XXXXXX','YYYYYY')).inE('assembled').outV() ---------------------------------------------------------------------- gremlin>

Hi Marc, Sorry for delay reply. Gremlin steps for my graph is below. (Sorry, I don't know how to attach file.) 1. schema groovy

Hi Roy, As I mentioned, I did not keep up with possibly new janusgraph-hbase features. From the HBase source, I see that HBase now has a "hbase.mapreduce.tableinput.mappers.per.region" config

you seem to run on cloud infra that reduces your requested 40 Gb to 33 Gb (see https://databricks.com/session_na20/running-apache-spark-on-kubernetes-best-practices-and-pitfalls). Fact of life.

Hi Marc Thanks for your immediate response. I've tried to set spark.yarn.executor.memoryOverhead=10G and re-run the task, and it stilled failed. From the spark task UI, I saw 80% of processing time is

``` Caused by: java.lang.IllegalArgumentException: Multiple entries with same key: Completeness_metric.Status=org.janusgraph.diskstorage.indexing.StandardKeyInformation@6bf65470 and

Hi Roy, There seem to be three things bothering you here: you did not specify spark.yarn.executor.memoryOverhead, as the exception message says. Easily solved. you seem to run on cloud infra that

Error message: ExecutorLostFailure (executor 1 exited caused by one of the running tasks) Reason: Container killed by YARN for exceeding memory limits. 33.1 GB of 33 GB physical memory used. Consider

I have the same promblem, have you ever solved it?

I have the same question. Anyone able to offer some light on this issue. There is (as usually) certain way of constructing Gremlin Query to get local index used, but there is not way to know it is

Hi Varun, Not a solution, but someone in the thread below explained the 257 magic number for OLAP on a Cassandra cluster: https://groups.google.com/g/janusgraph-users/c/IdrRyIefihY Marc Op vrijdag 4

Hi, I am facing this same issue. I am using SparkGraphComputer to read from Janusgraph backed by cassandra. `g.V().count()` takes about 3 minutes to load just two rows that I have in the graph. I see

pawan, can you check for following in your logs Loaded unidentified ReadMarker start time... seems your readmarker is starting from 1970. so it tries to read changes since then Regards, Sandeep

The problem of using custom value for null is that we need to choose a value for each data type, and hope that nobody will try to use this particular value. I suppose it is feasible for data type like

No, null support is an optional feature for graph providers. JanusGraph does not allow null value and I don’t think it will be supported (in near future). Apart from the solution suggested by Marc,

Hi Marc, Thank you for your response. If I understand correctly, with TinkerPop 3.5 I will be able to sort on property with missing values. It is a good news. Do you know it JanusGraph 0.6.0 will be

Hi Toom, No solution, but the exception that you mention comes from TinkerPop: https://github.com/apache/tinkerpop/blob/b4928e1262174a68c3dc1f3234d4340e266f8d98/docs/src/upgrade/release-3.5.x.asciidoc
