Run Apache Sqoop jobs by using .NET SDK for Apache Hadoop in HDInsight

Learn how to use the Azure HDInsight .NET SDK to run Apache Sqoop jobs in HDInsight to import and export between an HDInsight cluster and an Azure SQL database or SQL Server database.


Although you can use the procedures in this article with either a Windows-based or Linux-based HDInsight cluster, they work only from a Windows client. To choose other methods, use the tab selector at the top of this article.

Use Sqoop on HDInsight clusters with the .NET SDK

The HDInsight .NET SDK provides .NET client libraries, so that it's easier to work with HDInsight clusters from .NET. In this section, you create a C# console application to export the hivesampletable to the Azure SQL Database table that you created earlier in this article.

Submit a Sqoop job

  1. Create a C# console application in Visual Studio.

  2. From the Visual Studio Package Manager console, import the package by running the following NuGet command:

     Install-Package Microsoft.Azure.Management.HDInsight.Job
  3. Use the following code in the Program.cs file:

     using System.Collections.Generic;
     using Microsoft.Azure.Management.HDInsight.Job;
     using Microsoft.Azure.Management.HDInsight.Job.Models;
     using Hyak.Common;
     namespace SubmitHDInsightJobDotNet
         class Program
             private static HDInsightJobManagementClient _hdiJobManagementClient;
             private const string ExistingClusterName = "<Your HDInsight Cluster Name>";
             private const string ExistingClusterUri = ExistingClusterName + "";
             private const string ExistingClusterUsername = "<Cluster Username>";
             private const string ExistingClusterPassword = "<Cluster User Password>";
             static void Main(string[] args)
                 System.Console.WriteLine("The application is running ...");
                 var clusterCredentials = new BasicAuthenticationCloudCredentials { Username = ExistingClusterUsername, Password = ExistingClusterPassword };
                 _hdiJobManagementClient = new HDInsightJobManagementClient(ExistingClusterUri, clusterCredentials);
                 System.Console.WriteLine("Press ENTER to continue ...");
             private static void SubmitSqoopJob()
                 var sqlDatabaseServerName = "<SQLDatabaseServerName>";
                 var sqlDatabaseLogin = "<SQLDatabaseLogin>";
                 var sqlDatabaseLoginPassword = "<SQLDatabaseLoginPassword>";
                 var sqlDatabaseDatabaseName = "<DatabaseName>";
                 var tableName = "<TableName>";
                 var exportDir = "/tutorials/usesqoop/data";
                 // Connection string for using Azure SQL Database.
                 // Comment if using SQL Server
                 var connectionString = "jdbc:sqlserver://" + sqlDatabaseServerName + ";user=" + sqlDatabaseLogin + "@" + sqlDatabaseServerName + ";password=" + sqlDatabaseLoginPassword + ";database=" + sqlDatabaseDatabaseName;
                 // Connection string for using SQL Server.
                 // Uncomment if using SQL Server
                 //var connectionString = "jdbc:sqlserver://" + sqlDatabaseServerName + ";user=" + sqlDatabaseLogin + ";password=" + sqlDatabaseLoginPassword + ";database=" + sqlDatabaseDatabaseName;
                 var parameters = new SqoopJobSubmissionParameters
                     Files = new List<string> { "/user/oozie/share/lib/sqoop/sqljdbc41.jar" }, // This line is required for Linux-based cluster.
                     Command = "export --connect " + connectionString + " --table " + tableName + "_mobile --export-dir " + exportDir + "_mobile --fields-terminated-by \\t -m 1"
                 System.Console.WriteLine("Submitting the Sqoop job to the cluster...");
                 var response = _hdiJobManagementClient.JobManagement.SubmitSqoopJob(parameters);
                 System.Console.WriteLine("Validating that the response is as expected...");
                 System.Console.WriteLine("Response status code is " + response.StatusCode);
                 System.Console.WriteLine("Validating the response object...");
                 System.Console.WriteLine("JobId is " + response.JobSubmissionJsonResponse.Id);
  4. To run the program, select the F5 key.


Linux-based HDInsight presents the following limitations:

  • Bulk export: The Sqoop connector that's used to export data to Microsoft SQL Server or Azure SQL Database does not currently support bulk inserts.

  • Batching: By using the -batch switch, Sqoop performs multiple inserts instead of batching the insert operations.
