Create a non-interactive authentication .NET HDInsight application

Run your Microsoft .NET Azure HDInsight application either under the application's own identity (non-interactive) or under the identity of the signed-in user of the application (interactive). This article shows you how to create a non-interactive authentication .NET application to connect to Azure and manage HDInsight. For a sample of an interactive application, see Connect to Azure HDInsight.

From your non-interactive .NET application, you need:


An HDInsight cluster. See the getting started tutorial.

Assign a role to the Microsoft Entra application

Assign your Microsoft Entra application a role, to grant it permissions to perform actions. You can set the scope at the level of the subscription, resource group, or resource. The permissions are inherited to lower levels of scope. For example, adding an application to the Reader role for a resource group means that the application can read the resource group and any resources in it. In this article, you set the scope at the resource group level. For more information, see Assign Azure roles to manage access to your Azure subscription resources.

To add the Owner role to the Microsoft Entra application

  1. Sign in to the Azure portal.
  2. Navigate to the resource group that has the HDInsight cluster on which you'll run your Hive query later in this article. If you have a large number of resource groups, you can use the filter to find the one you want.
  3. On the resource group menu, select Access control (IAM).
  4. Select the Role assignments tab to see the current role assignments.
  5. At the top of the page, select + Add.
  6. Follow the instructions to add the Owner role to your Microsoft Entra application. After you successfully add the role, the application is listed under the Owner role.

Develop an HDInsight client application

  1. Create a C# console application.

  2. Add the following NuGet packages:

    • Install-Package Microsoft.Azure.Common.Authentication -Pre
    • Install-Package Microsoft.Azure.Management.HDInsight -Pre
    • Install-Package Microsoft.Azure.Management.Resources -Pre
  3. Run the following code:

    using System;
    using System.Security;
    using Microsoft.Azure;
    using Microsoft.Azure.Common.Authentication;
    using Microsoft.Azure.Common.Authentication.Factories;
    using Microsoft.Azure.Common.Authentication.Models;
    using Microsoft.Azure.Management.Resources;
    using Microsoft.Azure.Management.HDInsight;
    namespace CreateHDICluster
        internal class Program
            private static HDInsightManagementClient _hdiManagementClient;
            private static Guid SubscriptionId = new Guid("<Enter your Azure subscription ID>");
            private static string tenantID = "<Enter your tenant ID (also called directory ID)>";
            private static string applicationID = "<Enter your application ID>";
            private static string secretKey = "<Enter the application secret key>";
            private static void Main(string[] args)
                var key = new SecureString();
                foreach (char c in secretKey) { key.AppendChar(c); }
                var tokenCreds = GetTokenCloudCredentials(tenantID, applicationID, key);
                var subCloudCredentials = GetSubscriptionCloudCredentials(tokenCreds, SubscriptionId);
                var resourceManagementClient = new ResourceManagementClient(subCloudCredentials);
                _hdiManagementClient = new HDInsightManagementClient(subCloudCredentials);
                var results = _hdiManagementClient.Clusters.List();
                foreach (var name in results.Clusters)
                    Console.WriteLine("Cluster Name: " + name.Name);
                    Console.WriteLine("\t Cluster type: " + name.Properties.ClusterDefinition.ClusterType);
                    Console.WriteLine("\t Cluster location: " + name.Location);
                    Console.WriteLine("\t Cluster version: " + name.Properties.ClusterVersion);
                Console.WriteLine("Press Enter to continue");
            /// Get the access token for a service principal and provided key.          
            public static TokenCloudCredentials GetTokenCloudCredentials(string tenantId, string clientId, SecureString secretKey)
                var authFactory = new AuthenticationFactory();
                var account = new AzureAccount { Type = AzureAccount.AccountType.ServicePrincipal, Id = clientId };
                var env = AzureEnvironment.PublicEnvironments[EnvironmentName.AzureCloud];
                var accessToken =
                    authFactory.Authenticate(account, env, tenantId, secretKey, ShowDialog.Never).AccessToken;
                return new TokenCloudCredentials(accessToken);
            public static SubscriptionCloudCredentials GetSubscriptionCloudCredentials(SubscriptionCloudCredentials creds, Guid subId)
                return new TokenCloudCredentials(subId.ToString(), ((TokenCloudCredentials)creds).Token);
