Hi @dprutean, Thank you for providing the details about the error you’re encountering while connecting to the Databricks Unity Catalog using the Databricks JDBC driver.
Let’s troubleshoot this step by step:
-
Check your connection string:
- The connection string you’ve shared appears to be in the correct format. However, let’s verify a few things:
- Replace
<hostname>
with the actual hostname or IP address of your Databricks cluster.
- Ensure that the
token
parameter contains a valid access token.
- Confirm that the
transportMode
is set to http
or https
based on your cluster configuration.
- Make sure the port number (usually 443) is correct.
- If you’ve double-checked these parameters and they are correct, proceed to the next step.
-
Update your JDBC driver:
- It’s essential to use the latest version of the Databricks JDBC driver to avoid compatibility issues. You can download the driver from the Databricks website.
- Replace your existing driver JAR file with the new one and restart your application or service that uses the JDBC driver.
- Test the connection again after updating the driver.
-
Network and firewall settings:
- Ensure that there are no network or firewall restrictions preventing your application from connecting to the Databricks Unity Catalog.
- Check if your network allows outbound connections to the Databricks cluster.
- Verify that the necessary ports (e.g., 443 for HTTPS) are open.
-
Additional information:
- Could you provide more context about your setup? For example:
- Are you running this from a specific programming language or tool (e.g., Python, Java, SQL client)?
- Are there any specific steps you’re following to connect to the Unity Catalog?
- Any additional logs or error messages you can share would be helpful.
Feel free to provide more details, and we’ll continue troubleshooting together! 😊
