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 ...

It is an important goal for us to realize the improvement of enterprise operation efficiency through large data technology, but this work is not easy for every enterprise. On January 21, "1 billion said TalkingData mobile Internet Industry index Data Report", a number of industry experts and senior talkingdata for us to share the release of large data value existing pits, and how we can solve. The so-called 1 billion said, refers to the TalkingData platform now covers 1.06 billion of mobile smart devices, including iOS, an ...

This series of articles is a learning record about the fundamentals of azure services development, and because of time constraints, the process of wishing to discuss and explore yourself is from scratch, to be able to develop basic programming for azure services. There may be a very deep topic relative to each topic, and I would like to have time to do it through other articles. 　　The positioning of this series is basically positioning, take 20-30 minutes, download the code first, follow the article, run to get the relevant experience. The previous article is about Azure queue storage, this is about ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

In the previous article, we learned more about SDS's work and operation process through SSDs Explorer. 　　In this article, we will explain in detail how to use the programmer's method to manipulate SDS. SDS provides SOAP and rest two kinds of interfaces, here we use rest+c# method to explain. 　　Soap is the same as it is, please check MSDN with interested students. Less gossip, let's take the example of creating authority, giving the "universal framework" of the rest Operation SDS: public s ...

Cloudera recently released a news article on the Rhino project and data at-rest encryption in Apache Hadoop. The Rhino project is a project co-founded by Cloudera, Intel and Hadoop communities. This project aims to provide a comprehensive security framework for data protection. There are two aspects of data encryption in Hadoop: static data, persistent data on the hard disk, data transfer, transfer of data from one process or system to another process or system ...

Blockchain is currently a relatively popular new concept, containing two concepts of technology and finance. From a technical point of view, this is a distributed database that sacrifices consistency efficiency and guarantees eventual consistency. Of course, this is one-sided. From an economic point of view, this kind of fault-tolerant peer-to-peer network just meets a necessary requirement of the sharing economy - a low-cost trusted environment.

Cloud computing is a hot-fired term this year, major IT giants: Amazon, Google, Microsoft, Yahoo, IBM and so on to test the water, the introduction of cloud computing platform and a variety of cloud computing service model to attract the public eye, not only large companies, small and medium-sized enterprises are swarming, and tasted the many benefits of cloud computing. 　　So what is cloud computing? In layman's terms. Cloud computing is a huge server cluster, according to user needs dynamic mobilization of resources, ...

It is estimated that by 2015, more than half of the world's data will involve hadoop--an increasingly large ecosystem around the open source platform, a powerful confirmation of this alarming figure. However, some say that while Hadoop is the hottest topic in the bustling Big data field right now, it is certainly not a panacea for all the challenges of data center and data management. With this in mind, we don't want to speculate about what the platform will look like in the future, nor do we want to speculate about what the future of open source technology will be for radically changing data-intensive solutions.
