Distributed File System

Figure 1-14 shows the Hadoop system http://www.aliyun.com/zixun/aggregation/14305.html Distributed storage and parallel computing architecture from the hardware architecture point of view, Hadoop system is running in a normal The distributed storage and parallel computing system of commercial server cluster.The cluster will have a master node used to control and manage the normal operation of the entire cluster and coordinate the management of each slave nodes in the cluster to complete the data storage and computing tasks.All from Section ...

Research on the mechanism of middle-stage recovery of cloud storage log structure file system Hou Hao Zhao is far from the cloud storage file system, complex retrieval and recycling processes cause the system to process user data degradation, based on the log structure of Distributed file systems (hdfs-based log-structured file System,hlfs), this paper proposes a method to improve the effective utilization of cloud storage space by means of efficient recycle management of system resources, and find out the usage of hlfs middle resources through bitmap marking, and realize the hlfs ...

The Hadoop tide is gradually sweeping across all of America's vertical industries, including finance, media, retailing, energy, and pharmaceuticals. Hadoop, while building up the concept of large data, also carries out real-time analysis of massive data, and finds the trend from the analysis to improve the profitability of the enterprise. As open source data management software, Apache Hadoop is primarily used to analyze a large number of structured and unstructured data in a distributed environment. Hadoop has been used in many popular ... including Yahoo,facebook,linkedin and ebay.

Microsoft's famous C + + master Herb Sutter wrote a heavyweight article in early 2005: "The free lunch is over:a fundamental Turn toward concurrency in Software",      Another major change in software development after OO is predicted-parallel computing. ...

Here is a general introduction to Hadoop. Most of this article is from the official website of Hadoop. One of them is an introduction to HDFs's PDF document, which is a comprehensive introduction to Hadoop.    My this series of Hadoop learning Notes is also from here step-by-step down, at the same time, referring to a lot of articles on the Web, to learn the problems encountered in Hadoop summarized. Anyway, let's talk about Hadoop ...

Recently looking at "hadoop:the definitive Guide", streaming data access to its distributed file system HDFs is not understandable. Stream based data read and write, too abstract, what is called based on flow, what is flow? Hadoop is written in the Java language, so to understand the streaming Data Access of Hadoop, you have to start with the Java streaming mechanism. Flow mechanism is also a Java and C + + in an important mechanism, through the flow allows us to ...

Design and implementation of a large amount of small XML data file processing technology based on Hadoop University Kong Xin This paper focuses on the following: 1 a distributed mass of small XML data processing system (distributed Massive smallxml files SYSTEM,DMSX), the main idea of the system is to use a large number of small data XML files in the Hadoop system for efficient processing. 2 The system through the use of producer-elimination ...

Research and optimization of batch file storage performance oriented to HDFs Nanjing Normal University Suyisu the main work and innovation of this paper are as follows: 1, on the basis of studying the source code of HDFS system, this paper introduces HDFs typical operation flow and backstage management work, analyzes the metadata architecture system and communication mechanism in HDFs, Some problems and defects of HDFS system in batch file processing are discussed. 2, in order to solve the problem of batch file storage, the mechanism of batch file storage and the process of reading and writing are reconstructed. When writing to a bulk user file, C ...
