Hadoop is a framework for building distributed applications. The Hadoop framework provides a stable and reliable set of interfaces for applications to be transparent. The implementation of this technology can be easily mapped/reduced programming paradigm. In this paradigm, an application is split into many small task blocks. Each such task block is executed or restarted by the computer of any node in the cluster. In addition, this paradigm provides a distributed file system that is used to store data on computers with high bandwidth between each other in the cluster. Mapping/attribution and distributed text ...

In this very complicated information age of the Internet, we have learned how to use the powerful tool of search engine to find the target information. For example, you can search for Valentine's Day on Google to find a girlfriend, and you will also look for a regular Cosmetic medical institutions (although a large part of advertising liar). So if your own website system needs to enable users to search for some important information, and can be structured to show to the user, the following nine Java search engine framework to share may be able to help you. 1, Java full-text search lead ...
