Hadoop cluster Building (2)

Purpose This article describes how to install, configure, and manage a meaningful hadoop cluster that can scale from a small cluster of several nodes to a large cluster of thousands of nodes. If you want to install Hadoop on a single machine, you can find the details here. Prerequisites Ensure that all required softw

Hadoop Python framework guide

(key, values): emit (key, sum (values ))Hardware These MapReduce components are executed on a random subset of approximately 20 GB of data. The complete dataset contains 1500 files. We use this script to select a random subset. It is important to keep the file name complete because the file name determines the value of n in the n-element of the data block. The Hadoop cluster contains five virtual nodes tha

Hadoop uses Eclipse in Windows 7 to build a Hadoop Development Environment

Hadoop uses Eclipse in Windows 7 to build a Hadoop Development Environment Some of the websites use Eclipse in Linux to develop Hadoop applications. However, most Java programmers are not so familiar with Linux systems. Therefore, they need to develop Hadoop programs in Windows, it summarizes how to use Eclipse in Wind

Compile the hadoop 2.x Hadoop-eclipse-plugin plug-in windows and use eclipsehadoop

Compile the hadoop 2.x Hadoop-eclipse-plugin plug-in windows and use eclipsehadoopI. Introduction Without the Eclipse plug-in tool after Hadoop2.x, we cannot debug the code on Eclipse. We need to package MapReduce of the written java code into a jar and then run it on Linux, therefore, it is inconvenient for us to debug the code. Therefore, we compile an Eclipse plug-in so that we can debug it locally. Afte

Hadoop learning notes (2) pseudo distribution mode configuration

We have introduced the installation and simple configuration of hadoop in Linux, mainly in standalone mode. The so-called standalone Mode means that no daemon process is required ), all programs are executed on a single JVM. Because it is easier to test and debug mapreduce programs in standalone mode, this mode is suitable for use in the development phase. Here we mainly record the process of configuring the hadoo

Talking about massive data processing from Hadoop framework and MapReduce model

computing model, and programmers can use Hadoop to write programs that run on computer clusters to handle massive amounts of data. In addition, Hadoop provides a distributed file System (HDFS) and distributed Database (Hbase) for storing or deploying data to individual compute nodes. So, you can think of it roughly:Hadoop=HDFS(file system, data storage technolog

Writing a Hadoop handler using python+hadoop-streaming

Hadoop Streaming provides a toolkit for MapReduce programming that enables Mapper and Reducer based on executable commands, scripting languages, or other programming languages to take advantage of the benefits and capabilities of the Hadoop parallel computing framework, To handle big data.All right, I admit the above is a copy.

modify:/etc/hostname In addition, we need to make sure that the host name and IP address of each machine can be correctly resolved. A simple test method is to ping the host name, for example, Ping Frank-2 on Frank-1. If you can ping it, OK! If the hosts cannot be correctly parsed, you can modify the/etc/hosts file. If the hosts are used as namenode, you need to add the IP addresses of all hosts in the cluster and their corresponding host names in the hosts file; if this machine is used as a
