U-SQL Credential Objects
The CREATE/ALTER/DROP CREDENTIAL statements are deprecated and have been removed. Use the credential management commandlets in the latest Azure Powershell.
See Set-AzureRmDataLakeAnalyticsCatalogCredential for information on creating and managing an Azure Data Lake Analytics catalog credential.
U-SQL’s data sources may require the specification of login credentials (username/password) if the data source is not using integrated authentication via Azure Active Directory. In order to provide secure management of these credentials, one has to use a combination of PowerShell script commands to encode and encrypt the password into the key store and then register the key store reference in the meta data service so it can be used when creating a data source object.
