Hi Rajesh,
The error messages you're encountering suggest there’s a mismatch between the user account trying to execute a command and the account that has permissions to do so on the Databricks cluster. This could be because the cluster is set up for a single user, but another account is trying to run commands.
Here are some approaches to troubleshoot:
Check the cluster configuration: Take a look at the settings for the cluster in question. Ensure that your user account, or the one you're intending to use, has the proper permissions set up.
Verify your user identity: Double-check that you are indeed logged in with the user account that's supposed to have access. Sometimes, it might just be a simple case of being logged in with the wrong credentials.
Roles and permissions: Databricks uses role-based access control (RBAC), so you might need to check that your role includes the permissions required to move data from bronze to silver.
Access Control Lists (ACLs): Databricks allows you to set fine-grained access control at different levels. Make sure that the ACLs for the data you're trying to access are correctly set to give you the necessary permissions.
Token issues: If you’re using a token for authentication, verify that it’s still valid and hasn’t expired.
Network Policies: Sometimes, network policies can restrict access to certain users. It’s worth confirming that there aren't any such policies blocking your access.
To find more detailed guidance on setting up permissions and troubleshooting these kinds of issues, Microsoft's documentation is a great resource. You might specifically want to look into the Databricks documentation on Microsoft Learn, which provides comprehensive guides and best practices for managing Databricks clusters and access control https://kb.databricks.com/en_US/all-articles
