Which of the following 5 languages are NODE, LUA, Python, Ruby, R, and which will be better applied in the 2014? I don't hesitate to choose R. 　　R is not only 2014, but also the protagonist for a longer period of time. 1. My programming background programmer, Architect, from the beginning of programming to today, has been convinced that Java is the language to change the world, Java has done, and has been very brilliant.

Introduction: It is well known that R is unparalleled in solving statistical problems. But R is slow at data speeds up to 2G, creating a solution that runs distributed algorithms in conjunction with Hadoop, but is there a team that uses solutions like python + Hadoop? R Such origins in the statistical computer package and Hadoop combination will not be a problem? The answer from the king of Frank: Because they do not understand the characteristics of R and Hadoop application scenarios, just ...

The explosive growth of data has put pressure on companies at the same time, the development of data-driven business philosophy, enterprises and other organizations have to pay attention to the role of data statistics and analysis, for statistical computing and graphical and born of the R language to cater to this huge demand, in order to help enterprises better grasp and use of R language, 　　Responding to the need for statistical programming in the big Data Age, Revolution Analytics launched a new toolkit to support R language.

"The Chinese don't like to buy games, but they extravagantly in the game," he said. 　　"Yodol, a company that has helped localize a variety of European and American Games, describes the characteristics of Chinese gamers." These game-consuming players, called "tyrants" in the player group, are also the main source of performance for Chinese game operations. In order for these "tyrants" to take out more real money, game operators do what they have to do. "Todo" is the most common means. They either provoke "tyrants" anger through the challenge, or "tyrants" as a "high play" status guide.

What we want to does in this short tutorial, I'll describe the required tournaments for setting up a single-node Hadoop using the Hadoop distributed File System (HDFS) on Ubuntu Linux. Are lo ...
