Problem with provisioning lakehouse via Terraform

[Masoomeh]

I am trying to provision the lakehouse on Azure using the Terraform template provided here: https://github.com/databricks/terraform-databricks-examples/tree/main/examples/adb-lakehouse. I have started from scratch and have only added a resource group, a storage account and a container in Azure before I run the Terraform code. As per documentation, I have also modified the content of "terraform.tfvars". After running the Terraform code, I get the following errors:

╷
│ Error: cannot create catalog: No metastore assigned for the current workspace.
│

I have checked in the portal and see that the metastore is created. The access connector is also created and is assigned the required role (Storage Blob Data Contributor). The workspace is also connected to the UC metastore. But what I don't find is the managed identity under "Storage Credentials" in Unity Catalog. I appreciate any input on this.

Hi @Masoomeh, I’m sorry to hear that you’re facing issues while provisioning the lakehouse on Azure using the Terraform template provided by Databricks. Based on the error messages you’ve shared, it seems that the metastore is not assigned to the current workspace.

I suggest you check if the metastore is assigned to the correct workspace. You can also try assigning the metastore to the workspace again and then running the Terraform code.

Regarding the managed identity under “Storage Credentials”, I’m not sure what you’re referring to. Could you please provide more information about this?

Also, I found a helpful link that provides detailed instructions on how to provision a lakehouse platform using Terraform on Azure. You can refer to this link to ensure that you have followed all the necessary steps correctly.
