In the past, Java developers relied on Web browsers as the front end of their applications. But the process is often frustrating: HTML is clumsy, JavaScript is slow and hard to use, and without debugging tools, it's a tough process to make your application compatible with all browsers. But now your gospel is coming, with the improvement of browser technology, especially after the adoption of HTML5, the above problems have been significantly improved. Let's take a look at the 5 benefits that HTML5 can bring to Java developers. 1, Cross-platform ...

It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...

Core TIP: A new generation of information services treats browsers and devices as the same client. The challenge now is to establish such services. Can I use native code to develop mobile applications or use Web technologies such as HTML and JavaScript for deployment? Developers have been divided on this issue.

Introduction to Namenode in Hadoop is like the heart of a human being, and it's important not to stop working. In the HADOOP1 era, there was only one namenode. If the Namenode data is missing or does not work, the entire cluster cannot be recovered. This is a single point in the Hadoop1 and a hadoop1 unreliable performance, as shown in Figure 1. 　　HADOOP2 solved the problem. The high reliability of HDFs in hadoop2.2.0 means that you can start 2 name ...
