This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

Several articles in the series cover the deployment of Hadoop, distributed storage and computing systems, and Hadoop clusters, the Zookeeper cluster, and HBase distributed deployments. When the number of Hadoop clusters reaches 1000+, the cluster's own information will increase dramatically. Apache developed an open source data collection and analysis system, Chhuwa, to process Hadoop cluster data. Chukwa has several very attractive features: it has a clear architecture and is easy to deploy; it has a wide range of data types to be collected and is scalable; and ...

In fact, starting with the Ubuntu10.04 version, canonical started to offer cloud services through Ubuntuone, offering 2GB of free online storage and, if you want more space, paying an extra fee to buy. Cloud computing in recent years from a somewhat vague concept, gradually rise to the use of the stage. 　　 　　This makes every it vendor see infinite Business opportunities, canonical naturally also refused to ignore this sumptuous feast. After Ubuntu10.04 tasted the sweetness of cloud computing, Ubu ...

From the Eucalyptus system website to see a news, learned that eucalyptus and rpath cooperation. And Rpath is a company that provides system software package installation.

As we all know, the big data wave is gradually sweeping all corners of the globe. And Hadoop is the source of the Storm's power. There's been a lot of talk about Hadoop, and the interest in using Hadoop to handle large datasets seems to be growing. Today, Microsoft has put Hadoop at the heart of its big data strategy. The reason for Microsoft's move is to fancy the potential of Hadoop, which has become the standard for distributed data processing in large data areas. By integrating Hadoop technology, Microso ...

When it comes to application programming, Android is like an elephant in a room for a designer. Many designers would prefer this to be iOS, where all anyone cares about is the iphone, the ipad and the app Store. And no one can ignore Android, which now has the biggest market share in smartphones and has been widely used in a variety of products ranging from tablets to e-readers.
