Hi @joe zhou​ Your storage account must be in the same region where you have created your databricks workspace.

Please check this once

Thanks Ajay. However, I've double checked, the storage account is in the same region:

And just adding that the access connector privilege has been granted as same as earlier steps indicated:

Well. I've successfully created a metastore in east us region with similar settings. So guess something wrong in east asia.

I see that East Asia is supported by UC https://learn.microsoft.com/en-us/azure/databricks/resources/supported-regions you can try my step-by-step manual regarding setting up UC https://community.databricks.com/s/feed/0D58Y00009hlj04SAA

Thanks Hubert. But no luck. Still same error message.

Btw, the storage abfss link should be:

<container_name>@<storage_account_name>.dfs.core.windows.net/

instead of

<storage_account_name>@<container_name>.dfs.core.windows.net/

I looked one more time and this region is not supported for UC https://docs.databricks.com/resources/supported-regions.html

Thanks for keep looking, however that's the region for AWS 🙂

I've got a confirmation below from Andrew Li that the issue will be fixed soon.

This is a bug, thanks for reporting it! Databricks engineers would address this soon.

Thanks, deeply appreciated
