Run Pig jobs using the .NET SDK for Hadoop in HDInsight

This document provides an example of using the .NET SDK for Hadoop to submit Pig jobs to a Hadoop on HDInsight cluster.

The HDInsight .NET SDK provides .NET client libraries that makes it easier to work with HDInsight clusters from .NET. Pig allows you to create MapReduce operations by modeling a series of data transformations. In this document, you learn how to use a basic C# application to submit a Pig job to an HDInsight cluster.


To complete the steps in this article, you need the following.

  • An Azure HDInsight (Hadoop on HDInsight) cluster (either Windows or Linux-based).


    Linux is the only operating system used on HDInsight version 3.4 or greater. For more information, see HDInsight retirement on Windows.

  • Visual Studio 2012, 2013, 2015 or 2017.

Create the application

The HDInsight .NET SDK provides .NET client libraries, which makes it easier to work with HDInsight clusters from .NET.

  1. From the File menu in Visual Studio, select New and then select Project.

  2. For the new project, type or select the following values:

    Property Value
    Category Templates/Visual C#/Windows
    Template Console Application
    Name SubmitPigJob
  3. Click OK to create the project.

  4. From the Tools menu, select Library Package Manager or Nuget Package Manager, and then select Package Manager Console.

  5. To install the .NET SDK packages, use the following command:

     Install-Package Microsoft.Azure.Management.HDInsight.Job
  6. From Solution Explorer, double-click Program.cs to open it. Replace the existing code with the following.

    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 SubmitPigJob()
                var parameters = new PigJobSubmissionParameters
                    Query = @"LOGS = LOAD '/example/data/sample.log';
                                LEVELS = foreach LOGS generate REGEX_EXTRACT($0, '(TRACE|DEBUG|INFO|WARN|ERROR|FATAL)', 1)  as LOGLEVEL;
                                FILTEREDLEVELS = FILTER LEVELS by LOGLEVEL is not null;
                                GROUPEDLEVELS = GROUP FILTEREDLEVELS by LOGLEVEL;
                                FREQUENCIES = foreach GROUPEDLEVELS generate group as LOGLEVEL, COUNT(FILTEREDLEVELS.LOGLEVEL) as COUNT;
                                RESULT = order FREQUENCIES by COUNT desc;
                                DUMP RESULT;"
                System.Console.WriteLine("Submitting the Pig job to the cluster...");
                var response = _hdiJobManagementClient.JobManagement.SubmitPigJob(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);
  7. To start the application, press F5.

  8. To exit the application, press ENTER.


As you can see, the .NET SDK for Hadoop allows you to create .NET applications that submit Pig jobs to an HDInsight cluster, and monitor the job status.
