Problem:

Users are experiencing errors while running notebooks in different workspaces

Solution:

To resolve this issue, follow these steps:
1. Check if the issue occurs on clusters where data_security_mode is set as 'SINGLE_USER'. If the workspace is not UC enabled, 'data_security_mode' should be 'LEGACY_SINGLE_USER_STANDARD'.
2. Verify the JSON for the clusters where the issue occurs to see if the cluster policy is forcing the use of 'SINGLE_USER' mode.
3. Check if the user is using a personal compute/policy that is forcing 'defaultValue': 'SINGLE_USER' instead of 'LEGACY_SINGLE_USER_STANDARD'.
