Hi all

First time user - hope this is the right spot.

My goal is to import and export to an onPrem Oracle database. To this end, I am attempting to upload the ojdbc8.jar to the cluster. This does not, however, go well. The error is:

The error text: "Library installation attempted on the driver node of cluster 0911-042011-ccvo6es and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: java.util.concurrent.ExecutionException: abfss:/jars/ojdbc8.jar has invalid authority"

I'm not sure how to proceed with this. I have made sure the ojdbc8.jar is from the latest bundle of the instant-client (v23), but to no avail.

Cluster: 15.4 LTS (includes Apache Spark 3.5.0, Scala 2.12) running from Azure, i.e an Azure DB service.

Currently: single user, single node.

Hope you guys can help.
