  • Blog Post: Managing Your HDInsight Cluster and .Net Job Submissions using PowerShell

    This post explains how best to manage an HDInsight cluster using a management console and Windows PowerShell. The goal is to outline how to create a simple cluster, provide a mechanism for managing an elastic service, and demonstrate how to customize the cluster creation. Before provisioning a cluster...
  • Blog Post: Managing Hive Job Submissions With PowerShell

    In my previous post, I talked about “ Managing Your HDInsight Cluster with PowerShell ”. In this post I made no mention of using Hive. I hope to re-address this balance by specifically talking about how you can submit Hive jobs from the same local management console. As before all the scripts mentioned...
  • Blog Post: Managing Your HDInsight Cluster with PowerShell

    An updated version of this post can be found here . This blog post provides a mechanism for managing an HDInsight cluster using a local management console through the use of Windows PowerShell. The goal is to outline how to configure the local management console, create a simple cluster, submit jobs...
  • Blog Post: Submitting Hadoop MapReduce Jobs using PowerShell

    As always here is a link to the “ Generics based Framework for .Net Hadoop MapReduce Job Submission ” code. In all the samples I have shown so far I have always used the command-line consoles. However this does not need to be the case, PowerShell can be used. The Console application which is used to...
  • Blog Post: Co-occurrence Approach to an Item Based Recommender Update

    In a previous post I talked about a Co-occurrence Approach to an Item Based Recommender , that utilized the Math.Net Numerics library. Recently the Math.Net Numerics library was updated to version 2.3.0. With this version of the library I was able to update the code to more efficiently read the Sparse...
  • Blog Post: Implementing a MapReduce Join with Hadoop and the .Net Framework

    I have often been asked how does one implement a Join whilst writing MapReduce code. As such, I thought it would be useful to add an additional sample demonstrating how this is achieved. There are multiple mechanisms one can employ to perform a Join operation, and the one to be discussed will be a Reduce...
  • Blog Post: C# MapReduce Based Co-occurrence Item Based Recommender

    As promised, to conclude the Co-occurrence Approach to an Item Based Recommender posts I wanted to port the MapReduce code to C#; just for kicks and to prove the code is also easy to write in C#. For an explanation of the MapReduce post review the previous article: http://blogs.msdn.com/b/carlnol/archive...
  • Blog Post: MapReduce Based Co-occurrence Approach to an Item Based Recommender

    In a previous post I covered the basics for a Co-occurrence Approach to an Item Based Recommender . As promised, here is the continuation of this work, an implementation of the same algorithm using MapReduce. Before reading this post it will be worth reading the Local version as it covers the sample...
  • Blog Post: Framework for .Net Hadoop MapReduce Job Submission configuration update

    To better support configuring the Stream environment whilst running .Net Streaming jobs I have made a change to the “ Generics based Framework for .Net Hadoop MapReduce Job Submission ” code. I have fixed a few bugs around setting job configuration options which were being controlled by...
  • Blog Post: Framework for .Net Hadoop MapReduce Job Submission Binary Output

    To end the week I decided to make a minor change to the “ Generics based Framework for .Net Hadoop MapReduce Job Submission ”. I have been doing some work on creating a co-occurrence matrix for item recommendations. I was going to map the process to a MapReduce job(s), then came across...
  • Blog Post: Framework for .Net Hadoop MapReduce Job Submission libjars update

    If you have been using the “ Generics based Framework for .Net Hadoop MapReduce Job Submission ” you may want to download the latest version of the code. The previous version of the code, when processing XML and Binary files, was dependent on a custom streaming JAR that contained the necessary...
  • Blog Post: Generics based Framework for .Net Hadoop MapReduce Job Submission

    Over the past month I have been working on a framework to allow composition and submission of MapReduce jobs using .Net. I have put together two previous blog posts on this, so rather than put together a third on the latest change I thought I would create a final composite post. To understand why lets...
  • Blog Post: Framework for Composing and Submitting .Net Hadoop MapReduce Jobs (Archived)

    An updated version of this post can be found at: http://blogs.msdn.com/b/carlnol/archive/2012/04/29/generic-based-framework-for-net-hadoop-mapreduce-job-submission.aspx If you have been following my blog you will see that I have been putting together samples for writing .Net Hadoop MapReduce jobs;...
  • Blog Post: Hadoop Streaming in F# and MapReduce (summary)

    With all my recent posts around Hadoop Streaming I thought it would be useful to summarize them into a single post. The main objective of these posts was to put together a codebase to enable F# developers to write Map/Reduce libraries through a simple API. The full code posting can be found here: http...
  • Blog Post: Hadoop XML Streaming and F# MapReduce

    So, to round out the Hadoop Streaming samples I thought I would put together an XML Streaming sample. As always the code can be found here: http://code.msdn.microsoft.com/Hadoop-Streaming-and-F-f2e76850 XML Streaming Reader So how does one stream in XML? If you read the Hadoop Streaming documentation...
  • Blog Post: Hadoop Streaming and Windows Azure Blob Storage

    One of the cool features of the Microsoft Distribution of Hadoop (MDH) is the native support for Windows Azure Blob Storage. When performing HDFS operations by default one can omit the scheme such that: hadoop fs -lsr /mobile Is equivalent to: hadoop fs -lsr hdfs:///mobile The commands are defaulting...
  • Blog Post: Hadoop Binary Streaming and F# MapReduce

    As mentioned in my previous post Hadoop Streaming not only supports text streaming, but it also supports Binary Streaming. As such I wanted to put together a sample that supports processing Office documents; more on support for PDF in a later post. As always the code can be downloaded from: http:...
  • Blog Post: MapReduce Tester: A Quick Word

    In my previous post I talked a little about testing the Hadoop Streaming F# MapReduce code; but it is worth saying a few words about the tester application. The complete code for this blog post and the F# MapReduce code can be found at: http://code.msdn.microsoft.com/Hadoop-Streaming-and-F-f2e76850 As...
  • Blog Post: Hadoop Streaming and F# MapReduce

    And now for something completely different. As you may know Microsoft has recently announced plans for a Hadoop adoption for both Windows Server and Windows Azure . You can find out more about Hadoop and Windows Azure at Apache Hadoop-based Services for Windows Azure and Availability of Community...
