Explanation
Create and grant permissions to service principal
If your selected the access method requires a service principal with adequate permissions, and you do not have one, follow these steps:
1. Create an Azure AD application and service principal that can access resources. Note the following properties:
* client-id: An ID that uniquely identifies the application.
* directory-id: An ID that uniquely identifies the Azure AD instance.
* service-credential: A string that the application uses to prove its identity.
2. Register the service principal, granting the correct role assignment, such as Storage Blob Data
3. Contributor, on the Azure Data Lake Storage Gen2 account.
