Because of the needs of the project, learning to use Hadoop, as with all the overheated technology, "big Data", "mass" such words on the internet over the sky flying. Hadoop is a very good distributed programming framework that is exquisitely designed and does not currently have the same level of weight as a substitute. It also touches on an internally used framework that encapsulates and customizes Hadoop, making it more responsive to business requirements. I also recently wanted to write some of the learning and use of Hadoop experience, but see the internet so flooded articles, I think to write a little note the same thing is really not ...

Research on the optimization method of Hadoop performance based on scheduler Liu; He Chen; Tang Hong in order to improve the scheduling performance of Hadoop Scheduler and shorten the task overall response time of Hadoop cluster, a dynamic scheduling improvement algorithm based on CPU occupancy rate is proposed. Firstly, this paper compares the traditional performance optimization methods of Hadoop, and points out that the key problem is the lack of dynamic and flexibility. On the basis of this, this paper analyzes the default task scheduling model of Hadoop, and puts forward a kind of CPU occupancy rate as the load index, which is the root when the task is distributed.

Research on TFIDF algorithm based on MapReduce programming model Zhao Weiyan Wang Jingyu with the rapid development of technology such as Internet, information processing has become an indispensable tool for people to obtain useful information, so it is very important to obtain useful information efficiently in large amount of information, so automatic text categorization technology is especially significant. The existing text categorization algorithm meets the bottleneck in time complexity and space complexity, and can not meet the needs of people, so a TFIDF algorithm based on Hadoop distributed platform is proposed, and the algorithm is given ...

The Open Source Vulnerability analysis tool can help open, comprehensive review of cloud security. Vulnerability analysis is only part of ensuring server security. 　　Clearly, it is a big step in the right direction to precisely define a vulnerability assessment policy. 1, the introduction of any security policy, vulnerability assessment is a very important aspect. 　　Now, attacks on Internet hosts are increasingly driven by interest, so they are more cunning and more widely distributed. It seems difficult to protect all the Web servers, but most of the attacks launched by hackers can be avoided.
