Manage Azure Data Lake Analytics using a Java app

This article describes how to manage Azure Data Lake Analytics accounts, data sources, users, and jobs using an app written using the Azure Java SDK.


  • Java Development Kit (JDK) 8 (using Java version 1.8).
  • IntelliJ or another suitable Java development environment. The instructions in this document use IntelliJ.
  • Create an Azure Active Directory (AAD) application and retrieve its Client ID, Tenant ID, and Key. For more information about AAD applications and instructions on how to get a client ID, see Create Active Directory application and service principal using portal. The Reply URI and Key is available from the portal once you have the application created and key generated.

Authenticating using Azure Active Directory

The code following snippet provides code for non-interactive authentication, where the application provides its own credentials.

Create a Java application

  1. Open IntelliJ and create a Java project using the Command-Line App template.
  2. Right-click on the project on the left-hand side of your screen and click Add Framework Support. Choose Maven and click OK.
  3. Open the newly created "pom.xml" file and add the following snippet of text between the </version> tag and the </project> tag:

Go to File > Settings > Build > Execution > Deployment. Select Build Tools > Maven > Importing. Then check Import Maven projects automatically.

Open and replace the existing code block with the following code:


import java.util.Collections;
import java.util.UUID;
