Connect to Blob storage from Azure Databricks SQL

So I would like to read a table from a CSV file on Azure Blob Storage in my own account, and load it into a table in Unity Catalog on databricks (hopefully using SQL).

I have tried this SQL command:

CREATE TABLE IF NOT EXISTS <table_name>;

COPY INTO <table_name>
FROM 'abfss://<container>@<storage_account>.dfs.core.windows.net/<filename>.csv'
FILEFORMAT = CSV
COPY_OPTIONS ('mergeSchema' = 'true');

But it gives me the following error:

Failure to initialize configuration for storage account <storage_account>.dfs.core.windows.net: Invalid configuration value detected for fs.azure.account.key

I ideally don't want to use an access token, but a role if possible (or short lived credentials) for authentication, but have no idea why this doesn't work.

    @Kaizad Wadia - Thanks for the question and using MS Q&A platform.

    This is excepted when you haven't used any credentials to access the Azure Data Lake Storage Gen2 account where you have the sample data.

    According to the document: Connect to Azure Data Lake Storage Gen2 and Blob Storage - The following credentials can be used to access Azure Data Lake Storage Gen2 or Blob Storage:

    • OAuth 2.0 with a Microsoft Entra ID service principal
    • Shared access signatures (SAS)
    • Account keys

    For the demo purpose, I had used Account keys option to just to show case the authentication can be used to access Azure Data Lake Storage Gen2.

    spark.conf.set(
        "fs.azure.account.key.<storage-account>.dfs.core.windows.net","<storage-account-access-key>")
