Terraform Error: cannot create metastore: Invalid JSON received

210 views Asked by Aniket Karajgikar At 13 September 2024 at 10:49

I am trying to create databricks metastore using Terraform by following documentation.

I tried below code:

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=3.74.0"
    }
    databricks = {
      source  = "databricks/databricks"
    }
  }
}
provider "databricks" {
   profile = var.databricks_connection_profile (DEFAULT conn profile was valid)
   host = data.azurerm_databricks_workspace.dbwdata.workspace_url
   #token= "*****" (I tried this)
   #config_file = <path of .databrickscfg>  (& this as well)
}
    


resource "databricks_metastore" "this" {
       provider = databricks.accounts
       name     = "mymeta"
       storage_root = format("abfss://%s@%s.dfs.core.windows.net/sandbox",
         "container",
         "samplestorage")
       force_destroy = true
       region        = var.azure_region
       depends_on = [
         module.databricks
        ]
       }

But I am getting below error:

Error: cannot create metastore: Invalid JSON received (1040 bytes): <!doctype html>Databricks - Sign inYou need to enable JavaScript to run this app.

The error message you're encountering suggests an issue related to authentication or access to the Databricks environment. Make sure it has the required permissions for the Service Principal (Account Admin) to create a Meta Store. follow the Ms doc about assigning account admin to SP.

Here is the updated code to create Metastore using Service Principal

    terraform {
      required_providers {
        databricks = {
          source = "databricks/databricks"
        }
      }
    }
    provider "azurerm" {
      features {}
    
      client_id       = "SP-App-ID"
      client_secret   = ",SP-secret"
      tenant_id       = "Tenant-ID"
      subscription_id = "Subscription-ID"
    }
    
    data "azurerm_resource_group" "this" {
      name = "Venkat"
    }
    
    data "azurerm_databricks_workspace" "this" {
      name                = "sample-databricks"
      resource_group_name = "Venkat"
    }
    
    provider "databricks" {
      alias               = "accounts"
      host                = "https://accounts.azuredatabricks.net"
      account_id          = "Workspace-account-ID"
      azure_tenant_id     = "Tenant-ID"
      azure_client_id     = "Client-ID"
      azure_client_secret = "secret"
    }
    
    resource "azurerm_databricks_access_connector" "unity" {
      name                = "venkatdatabricksmi"
      resource_group_name = data.azurerm_resource_group.this.name
      location            = data.azurerm_resource_group.this.location
      identity {
        type = "SystemAssigned"
      }
    }
    resource "azurerm_storage_account" "unity_catalog" {
      name                     = "thejadatabricksdemo"
      resource_group_name      = data.azurerm_resource_group.this.name
      location                 = data.azurerm_resource_group.this.location
      account_tier             = "Standard"
      account_replication_type = "GRS"
      is_hns_enabled           = true
    }
    
    resource "azurerm_storage_container" "unity_catalog" {
      name                  = "venkat-container"
      storage_account_name  = azurerm_storage_account.unity_catalog.name
      container_access_type = "private"
    }
    
    resource "azurerm_role_assignment" "example" {
      scope                = azurerm_storage_account.unity_catalog.id
      role_definition_name = "Storage Blob Data Contributor"
      principal_id         = azurerm_databricks_access_connector.unity.identity[0].principal_id
    }
    
    resource "databricks_metastore" "this" {
      provider = databricks.accounts
      name     = "primary"
      storage_root = format("abfss://%s@%s.dfs.core.windows.net/",
        azurerm_storage_container.unity_catalog.name,
        azurerm_storage_account.unity_catalog.name)
      force_destroy = true
      region        = "eastus"
    }
