Hello all,
I'm trying to setup the best solution for the integration of Snowflake and Neo4j. Idea is that we use SNowflake as a source to update the Neo4j graph with the correct nodes.
I followed the instructions on https://github.com/neo4j-contrib/neo4j-dwh-connector to setup a Spark Submit job. Using the connector for Spark 3.x which I uploaded in Databricks and the configuration as supplied in the github documentation. I changed the configuration to match the DBFS path of my uploaded connector and the same for the json config file which is very simple at the moment.
Databricks choosen configuration: Driver: Standard_DS3_v2, Workers: Standard_DS3_v2, 0 workers, 10.4 LTS (includes Apache Spark 3.2.1, Scala 2.12)
In the logs I can see which modules are loaded:
modules in use:
net.snowflake#snowflake-ingest-sdk;0.10.3 from central in [default]
net.snowflake#snowflake-jdbc;3.13.15 from central in [default]

:: evicted modules:

But then I receive an error:

Anyone an idea how to solve this?
Thanks in advance!
