There is a concept of an abstract file system in Hadoop that has several different subclass implementations, one of which is the HDFS represented by the Distributedfilesystem class. In the 1.x version of Hadoop, HDFS has a namenode single point of failure, and it is designed for streaming data access to large files and is not suitable for random reads and writes to a large number of small files. This article explores the use of other storage systems, such as OpenStack Swift object storage, as ...

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 rise of mobile devices is bringing a new revolution to the Internet, although the principles of mobile web design will not change much, but there are obvious differences. At least one point is very different, the current mobile device network speed can not be compared to broadband, the other mobile Web page presentation is also a variety of ...

In this column, I will highlight how to execute the rule application on the cloud. Can WEB applications take advantage of the rules engine that will be deployed to the public cloud? If so, which rule integration patterns will we use? Which ODM components will we deploy? How do we expect to achieve performance levels? What challenges are waiting for us? These are the questions this column would like to answer for two widely used cloud products: Google App engine™ and Amazon Web services™. This column describes a personal discovery tour ...

Web site performance is an objective indicator, can be reflected in response time, throughput, concurrency, performance counters and other technical indicators. 1. Performance Test Indicator 1.1 response time refers to the time that the application takes to perform an operation, from the time it takes to send the request to the final receipt of the response data. The following is a list of common operational response schedules for the system.

The industry is rapidly embracing cloud technology to improve internal efficiency and launch new cloud services. In such a context, the ability to quickly and efficiently integrate, aggregate, and provide multiple classes of differentiated cloud services is critical to cloud service providers. The Proxy service platform also plays an important role here. They provide a pre-built environment for exposing and reselling cloud services. Managing new service providers in this proxy service platform means managing User Configuration, service versioning, service activation, service deletion, and so on. To get faster service activation and better market response, you can use IBM ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...
