"The Internet World" is a series of questions that have come up since Intel announced in March this year that it was buying $740 million for big data [note] software solution provider Cloudera's 18% stake: for example, two companies have their own Apache Hadoop distributions, 　　How are the two products and services integrated? is the Legacy Apache Hadoop Intel distribution user's follow-up service guaranteed? How has Intel changed its strategy on big data? And so on. May 8, Intel and Cloudera in ...

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 ...

The development of spark for a platform with considerable technical threshold and complexity, spark from the birth to the formal version of the maturity, the experience of such a short period of time, let people feel surprised. Spark was born in Amplab, Berkeley, in 2009, at the beginning of a research project at the University of Berkeley. 　　It was officially open source in 2010, and in 2013 became the Aparch Fund project, and in 2014 became the Aparch Fund's top project, the process less than five years time. Since spark from the University of Berkeley, make it ...

The problem, as the New York Times pointed out in a previous article in its publication: All of the hardware is being powered up and running, even including industrial cooling and standby diesel generators emitted into the atmosphere and other pollutants. At the same time, even if data center operators continue to reward those energy-saving measures, continuous uptime over its energy efficiency is often running at full power, but there are still many servers apparently idle or apparently underutilized. As the volume of data continues to grow, there will also be a significant amount of pollution from the data center. This, as the "...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

Cloud computing so far has been considered hot speculation, but still not been fried, and now the big data began to get hot again. Most of the media can see that the era of cloud computing is coming, and now some people think the big data era has arrived. The menace of cloud computing has left many CIOs at large and medium-sized companies feeling anxious because the new challenges brought by cloud computing to CIOs are clearly out there. The CIOs on the enterprise did not take the training course of cloud computing shortly afterwards, and on the other side they heard another wave of big data coming. CIO who study ...
