User Account Requirements 

In order to access the Azure Data Lake, an Application Account with sufficient privileges must be supplied. The following fields must be configured in order to set up a new Data Lake connection:

Get an Application Account

1.  See Microsoft's Use portal to create an Azure Active Directory application and service principal that can access resources for the steps on how to properly create an Application ID and its key.


Make sure to write down your Application Key at the time of creation. It will not be shown again after you exit the portal.  Important: Make sure to grant the necessary Reader access to your application.

2.  This connector uses a OAuth 2.0 authorization via Token End Point. Azure will supply this authorization. See Microsoft's Step 4: Get the OAuth 2.0 token endpoint (only for Java-based applications)

     After these steps are completed, you will have created a valid Application.

3.  Make sure to grant Read and Execute access (at least) to files and folders to crawl. See Microsoft's Step 3: Assign the Azure AD application to the Azure Data Lake Store account file or folder.

4.  Follow the recommended Advance Features of the Data Lake File Explorer to recursively apply the same parent folder permissions to sub-folders using the "Apply folder permissions to sub-folders" option. 

     The Application does not have access to any specific folder. Aspire will log this warning during the crawl process

Windows or Linux

The Azure Data Lake connector runs on either a Windows or Linux instance of Aspire.
