MapReduce: Simple data processing on Super large cluster

MapReduce: Simple data processing on large cluster

Getting Started with Hadoop

Hadoop is a Java implementation of Google MapReduce. MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Just as Java programmers can do without memory leaks, MapReduce's run-time system solves the distribution details of input data, executes scheduling across machine clusters, handles machine failures, and manages communication requests between machines. Such a pattern allows programmers to be able to do nothing and ...

Automated Linux Cloud Installation

One of the features of cloud computing is the ability to move applications from one processor environment to another. This feature requires a target operating system to receive it before moving the application. Wouldn't it be nice if you could automate the installation of a new operating system? A well-known feature of the intel™ architecture system is the ability to install Linux automatically. However, installing Linux automatically is a tricky issue for System P or IBM power BAE using the hardware management console. This article discusses the solution of ...

A "fantasy" Docker Libcontainer Code reading tour

Editor's note: The last period of time reproduced in the "5 minutes to understand docker! "Very popular, a short 1500 words, let everyone quickly understand the Docker." Today, I saw the author make a new novel, and immediately turned over. The reason to call this code reading as a fantasy trip is because the author Liu Mengxin (@oilbeater) in the process of reading Docker source, found a few interesting things: from the code point of view Docker did not start a new development mechanism, but the existing tested isolation security mechanism to use the full use, Including Cgroups,c ...

Map reduce-the free lunch isn't over?

Microsoft's famous C + + master Herb Sutter wrote a heavyweight article in early 2005: "The free lunch is over:a fundamental Turn toward concurrency in Software",      Another major change in software development after OO is predicted-parallel computing. ...

Cloud computing with Linux and Apache Hadoop

Companies such as IBM®, Google, VMWare and Amazon have started offering cloud computing products and strategies. This article explains how to build a MapReduce framework using Apache Hadoop to build a Hadoop cluster and how to create a sample MapReduce application that runs on Hadoop. Also discusses how to set time/disk-consuming ...

MapReduce: The free lunch isn't over yet?

Microsoft's famous C + + master Herb Sutter wrote a heavyweight article in early 2005: "The free lunch is over:a fundamental Turn toward concurrency in Software", Another major change in software development after OO is predicted-parallel computing. The era of software development under Moore's Law has a very interesting phenomenon: "Andy giveth, and Bill ...
