Tez - Build, Install, Configure and Run Apache Hadoop 2.2.0 in Microsoft Windows OS - SrcCodes.
Good news for Hadoop developers who want to use Microsoft Windows OS for their development activities. Finally Apache Hadoop 2.2.0 release officially supports for running Hadoop on Microsoft Windows as well. But the bin distribution of Apache Hadoop 2.2.0 release does not contain some windows native components (like winutils.exe, hadoop.dll etc). As a result, if we try to run Hadoop in windows, we'll encounter ERROR util.Shell: Failed to locate the winutils binary in the hadoop binary path. In this article, I'll describe how to build bin native distribution from source codes, install, configure and run Hadoop in Windows Platform.

Edit Path Variable to add bin directory of Cygwin (say C:\cygwin64\bin), bin directory of Maven (say C:\maven\bin) and installation path of Protocol Buffers (say c:\protobuf). f.
G. H. A. Natalino Busa: Hadoop 2.0 beyond mapreduce: A distributed generic application OS for data crunching. Central on the original concept of Hadoop is the map-reduce paradigm/architecture. Mapreduce is based on two entities: one Job Tracker and a series of Task tracker (mostly one per data worker). This paradigm is powerful but this is only one way to accomplish distributed computing. This approach is batch oriented and is targeting crunching large files making the most use of data locality. However good mapreduce is for a specific class of distributed computing tasks, it is not a general pattern that applies well for all applications. Rather than forcing the mapreduce paradigm on each application running on the cluster hadoop 2.0 and yarn focus on the idea how to separate the hadoop application (mapreduce) from a more general problem of resource monitoring and management (yarn).
Central to hadoop map-reduce v1 is the job tracker. This is a single cluster agent which has to take care of several functions. When the client wants to execute a new job. Conclusion References, Acknowledgments. Blogs. We’ve made a nice fix to the Templeton job submission service that runs on the HDInsight clusters for remote job submission. We’ve talked with a number of customers who want to be able to get access to the logs for the jobs remotely as well. This typically requires access directly to the cluster. We’ve updated Templeton to support dropping the job logs directly into ASV as part of the status directory. The way to do this is to pass “enablelogs” as a query string parameter set to true. Upon job completion, the logs will be moved into the status directory, under a logs folder with the following structure: $log_root/list.xml (summary of jobs) $log_root/stderr (frontend stderr) $log_root/stdout (frontend stdout) $log_root/$job_id (directory home for a job) $log_root/$job_id/job.xml.html $log_root/$job_id/$attempt_id (directory home for a attempt) $log_root/$job_id/$attempt_id/stderr $log_root/$job_id/$attempt_id/stdout $log_root/$job_id/$attempt_id/syslog.

Hadoop for .NET Developers: Setting Up a Desktop Development Environment - Data Otaku. NOTE This post is one in a series on Hadoop for .NET Developers. If you are a .NET developer, you will want to setup a desktop development environment with the following components: Having these components installed on your desktop will allow you to develop against Hadoop locally as well as against a remote cluster (whether on-premise on in the cloud). You might be able to get away with not installing Hadoop locally, but most of the .NET-oriented documentation I’ve found assumes this is your setup.
I will assume you are comfortable installing Visual Studio on your own and the NuGet site provides simple enough installation options. I do recommend installing Visual Studio and NuGet first and then making sure your system is up-to-date with patches before proceeding with the Hadoop installation. The Hadoop installation is very straightforward. S Tech Journal: Top 500 MSDN Links from Stack Overflow Posts. I explained in In my previous post how to run C# Map/Reduce jobs in Hadoop on Azure to find the top Namespaces in Stackoverflow posts. After that, I did another Map/Reduce on the Stackoverflow data dump and here is the list of Top 500 MSDN Urls we all referred in our Stackoverflow posts.
This is just done on partial post data from the Stakoverflow data dump . Thought about sharing the same as it looked very interesting. I used the following Mapper to parse this, almost the same as in the previous example, with a regex to parse the URLs. Here are the URLs and number of times they got quoted. S Tech Journal: Analyzing some ‘Big’ Data Using C#, Azure And Apache Hadoop – A Stack Overflow .NET Namespace Popularity Finder. Time to do something meaningful with C#, Azure and Apache Hadoop. In this post, we’ll explore how to create a Mapper and Reducer in C#, to analyze the popularity of namespaces in the Stack overflow posts. Before we begin, let us explore Hadoop and Map Reduce concepts shortly. A Quick Introduction To Map Reduce Map/Reduce is a programming model to process insanely large data sets, initially implemented by Google .
The Map and Reduce functions are pretty simple to understand. Map(list) –> List of Key, Value The Map function will process a data set and splits the same to multiple key/value pairs Aggregate, Group The Map/Reduce framework may perform operations like group,sort etc on the output of Map function. The interesting aspect is, you can use a Map/Reduce framework like Apache Hadoop, to hierarchically parallelize Map/Reduce operations on a Big Data set. There is an excellent visual explanation from Ayende @ Rahien if you are new to the concept.

24HOP/SQLRally - Fitting Microsoft Hadoop Into Your Enterprise BI Strategy Small Bites of Big Data Cindy Gross, SQLCAT PM The world of #bigdata and in particular #Hadoop is going mainstream. Hadoop generally falls into the NOSQL realm. Hive is a database which sits on top of Hadoop’s HDFS (Hadoop Distributed File System).
You may keep your source data outside HDFS and bring it in only for the duration of a project. So far I’ve been talking as if big data = Hadoop. At its core Hadoop has the file system HDFS which sits on top of the Windows or Linux file system and allows data to be mapped over many nodes in a Hadoop cluster. So when would you use Hadoop? Often you ask about the 4 “Vs” when deciding whether to use Hadoop - volume, velocity, variety, variability. Microsoft is taking the existing Apache Hadoop code and making sure it runs on Windows. We offer visualization through PowerPivot, Power View, and the Excel Hive ODBC Add-in.
