What we want to does in this tutorial, I'll describe the required tournaments for setting up a multi-node Hadoop cluster using the Hadoop Distributed File System (HDFS) on Ubuntu Linux. Are you looking f ...

Hadoop is a Java implementation of Google MapReduce. MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Just as Java programmers can do without memory leaks, MapReduce's run-time system solves the distribution details of input data, executes scheduling across machine clusters, handles machine failures, and manages communication requests between machines. This ...

Save space, straight to the point. First, use the virtual machine VirtualBox to configure a Debian 5.0. Debian is always the most pure Linux pedigree in open source Linux, easy to use, efficient to run, and a new look at the latest 5.0, and don't feel like the last one. Only need to download Debian-501-i386-cd-1.iso to install, the remaining based on the Debian Strong network features, can be very convenient for the package configuration. The concrete process is omitted here, can be in ...

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 ...

1 compression in general, the computer processing of data exist some redundancy, at the same time, the data, especially the correlation between adjacent data, so you can through some different from the original encoding of the special encoding method to save data, so that the data occupy a small amount of storage space, this process is generally called compression. The concept of compression corresponds to decompression, the process of restoring compressed data from a special encoding to the original data. Compression is widely used in mass data processing, compression of data files, can effectively reduce the space required to store files, and speed up data on the network or to ...
