Access Azure Data Lake Storage Gen1 automatically with your Azure AD credentials

December 5-11, 2018: Version 2.86

You can now authenticate automatically to Azure Data Lake Storage Gen1 from Azure Databricks clusters using the same Azure Active Directory (Azure AD) identity that you use to log into Azure Databricks.

Simply enable your cluster for Azure AD credential passthrough, and commands that you run on that cluster will be able to read and write your data in Azure Data Lake Storage Gen1 without requiring you to configure service principal credentials for access to storage.


The ability to access Azure Data Lake Storage Gen1 using your Azure AD credentials is in Public Preview. It requires Databricks Runtime 5.1, which is currently in Beta but will soon be generally available.

For more information, see Access automatically with your Azure Active Directory credentials.
