Hadoop is an open source distributed parallel programming framework that realizes the MapReduce computing model, with the help of Hadoop, programmers can easily write distributed parallel program, run it on computer cluster, and complete the computation of massive data. This paper will introduce the basic concepts of MapReduce computing model, distributed parallel computing, and the installation and deployment of Hadoop and its basic operation methods. Introduction to Hadoop Hadoop is an open-source, distributed, parallel programming framework that can be run on a large scale cluster by ...

Last week, we described how to evaluate the code used to extend cloud applications. Now, we're going to look at the coding and system-change strategies that are likely to make the system more vulnerable over time. Because of the seemingly never-ending development requirements of the CRM system, the durability of our code will be a key factor in the long-term smooth running of these systems. But before I begin, I need to declare that the usages and terms I cite apply only to the salesforce.com environment, and that other applications and platforms use different types of association ...

MapReduce: Simple data processing on large cluster

Page refactoring engineers have a special position in the Web research and development world, and his basic skill is to restore the design concept. The single Foundation is not enough, still need to focus on forward-looking web technology, participate in page dynamic design, sometimes even need to deal with some basic visual design work, and some refactoring engineers may also have server-side development capabilities or canvas, SVG and other graphics processing capabilities. 　　Abroad, this position is generally called Web Designer, but we prefer to call ourselves "page Aberdeen". If you have done page related ...
