Good morning,
I am able to create and test successfully a connection from ArcGIS Pro to Databricks via OBDC. But when I click in the connection to open it and see its content it returns an "Unspecified error"
From a Support Services case - "Databricks is not officially supported by Esri, so the interaction between the Databricks platform and ArcGIS applications may be uncertain."
And there is an enhancement request July 2025: ENH-000170840 : Add Databricks as a supported cloud data warehouse connection for ArcGIS Pro.
