Just find the Linux apropos that have never been used, and directly enter apropos [keyword] to view commands related to keyword functions. The command actually completes the search for descriptions of other commands, lists the relevant commands, and the commands that don't necessarily appear are what you want, but can help you recall useful commands from them. Linux apropos use method, man apropos to see for himself. Linux Apropos example with Linux apropos check ...

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 ...

Hadoop is an open source distributed parallel programming framework that realizes the MapReduce computing model, with the help of Hadoop, programmers can easily write distributed parallel program, run it on computer cluster, and complete the computation of massive data. This paper will introduce the basic concepts of MapReduce computing model, distributed parallel computing, and the installation and deployment of Hadoop and its basic operation methods. Introduction to Hadoop Hadoop is an open-source, distributed, parallel programming framework that can run on large clusters.
