How to install Nutch and Hadoop to search for Web pages and mailing lists, there seem to be few articles on how to install Nutch using Hadoop (formerly DNFs) Distributed File Systems (HDFS) and MapReduce. The purpose of this tutorial is to explain how to run Nutch on a multi-node Hadoop file system, including the ability to index (crawl) and search for multiple machines, step-by-step. This document does not involve Nutch or Hadoop architecture. It just tells how to get the system ...

The performance of the MapReduce paradigm is not always ideal in the face of large-scale computational-intensive algorithms. 　　To address its bottlenecks, a small start-up team built a product called PARALLELX, which will bring significant improvements to the Hadoop task by leveraging the computing power of the GPU. Parallelx's co-founder, Tony Diepenbrock, says this is a "GPU compiler that translates user code written in Java into OpenCL and is shipped on Amazon's AWS GPU Cloud ...

The large data in the wall are registered as dead data. Large data requires open innovation, from data openness, sharing and trading, to the opening of the value extraction ability, then to the foundation processing and analysis of the open platform, so that the data as the blood in the body of the data society long flow, moisture data economy, so that more long tail enterprises and data thinking innovators have a colorful chemical role, 　　To create a golden age of big data. My large data research trajectory I have been 4-5 years of mobile architecture and Java Virtual Machine, 4-5 years of nuclear architecture and parallel programming system, the last 4-5 years also in pursuit ...

After MySQL was acquired by Oracle, the industry has never stopped talking about the Open-source database, and the voice of PostgreSQL will be replaced as the most popular Open-source database. However, from the Db-engines rankings, the gap between PostgreSQL and MySQL is far more than "a few floors" so high (PostgreSQL not score a fraction of MySQL). Looking at the entire list of 193 databases, we will find that the NoSQL database has accounted for most of the traditional relationship ...

One of the core concepts of cloud computing is that resources and software functions will be released in the form of services. Different services usually need mutual assistance through message and communication. Because synchronous message communication is too inefficient, we only need to consider asynchronous communication. For example, Java Message Service is a standard messaging mode on the J2EE platform. J2EE applications can create, send, receive, and read messages through JMS. Asynchronous messaging today has become service-oriented ...
