@AJITH KUMAR RAI Thank you for providing additional information. Based on your response, it seems that you have already tried several approaches to resolve the issue, but you are still encountering the "AuthTypeNotSupported" error when trying to read data with the notebook using the MSI linked service.
It's possible that the "AuthTypeNotSupported" error is caused by a limitation in the current implementation of Synapse Analytics. According to the ticket you mentioned, this functionality may not be supported at this time.
However, there are a few workarounds you can try:
- Use a different authentication method: Instead of using MSI, you can try using a different authentication method, such as a shared access signature (SAS) token or a connection string. You can create a new linked service with the appropriate authentication method and test the Scala code block with the new linked service.
- Use a different notebook: You can try using a different notebook to see if the issue is specific to the current notebook. You can create a new notebook and test the Scala code block with the new notebook.
- Reach out to Azure support: If the issue persists, you can try reaching out to Azure support for further assistance. They may be able to provide additional insights or workarounds to help you resolve the issue.
I hope this helps. Do let us know if you any further queries.
