Setting up a Hadoop Cluster on Mac OS X Mountain. I have been working on using the Hadoop platform as an infrastructure for distributed testing of iOS applications.
So I had to set up a Hadoop cluster for my experiment on Mac OS X. Mac OS X has its root from UNIX, so in theory, we should be able to set up Hadoop under the Mac OS X environment,... right? This post provides steps that I took to set such environment up. Prerequisites Java Java is required to be installed to be able to run Hadoop on each node in the cluster. Hadoop relies on SSH to communicate between nodes in the cluster and to perform cluster-wide operations. On Mac OS X, we first need to enable Remote Logins by Go to System PreferencesGo to SharingCheck at Remote Logins optionAlso noted the Computer Name here that it will be used as a HOST_NAME during the set up. Running Hadoop On Ubuntu Linux (Single-Node Cluster)
In this tutorial I will describe the required steps for setting up a pseudo-distributed, single-node Hadoop cluster backed by the Hadoop Distributed File System, running on Ubuntu Linux.
Hadoop is a framework written in Java for running applications on large clusters of commodity hardware and incorporates features similar to those of the Google File System (GFS) and of the MapReduce computing paradigm. Hadoop’s HDFS is a highly fault-tolerant distributed file system and, like Hadoop in general, designed to be deployed on low-cost hardware. It provides high throughput access to application data and is suitable for applications that have large data sets. The main goal of this tutorial is to get a simple Hadoop installation up and running so that you can play around with the software and learn more about it.
This tutorial has been tested with the following software versions: Apache ZooKeeper - Home. HBase Shell Exercises User Guide - ICPAD 2010 - Clouds and Cloud Technologies for Data Intensives Sciences. Commands Guide. Overview All hadoop commands are invoked by the bin/hadoop script.

Eclipse is a popular choice thanks to its broad user base and multitude of available plugins. Hadoop Tutorial. Introduction Hadoop is an open source implementation of the MapReduce platform and distributed file system, written in Java.
This module explains the basics of how to begin using Hadoop to experiment and learn from the rest of this tutorial. It covers setting up the platform and connecting other tools to use it. IntelliJ Project for Building Hadoop – The Definitive Guide Examples. I have been studying Hadoop – The Definitive Guide by Tom White and started building the sample applications with the Makefile I discussed in my last blog. Although the Makefile approach works, I decided to try using the IntelliJ Community Edition IDE to build the examples in any given chapter all at once. This time around I’ll walk you through a procedure to create an IntelliJ project for building Hadoop applications. Install IntelliJ If you don’t have it already, you can get the latest version of IntelliJ Community Edition here. Select the package for your operating system of choice, either Mac OS or Linux, then install IntelliJ by placing the package contents in your directory of choice.
Install the Sample Code First you need the sample code from the Hadoop book. Create a Project For this example we build the apps from Chapter 3.

Step 1: Creating a designated hadoop user on your system This isn't -entirely- necessary, but it's a good idea for security reasons. To add a user, go to: System Preferences > Accounts Click the "+" button near the bottom of the account list. You may need to unlock this ability by hitting the lock icon at the bottom corner and entering the admin username and password. When the New account window comes out enter a name, as short name and a password. Name: hadoop Short name: Hadoop Password: MyPassword (well you get the idea) Once you are done, hit "create account". Step 2: Install/Configure Preliminary Software Before installing Hadoop, there are a couple things that you need make sure you have on your system.
Java, and the latest version of the JDK SSH Because OS X is awesome, you actually don't have to install these things. Updating Java Open up the Terminal application. Applications > Utilities > Terminal Next check to see the version of Java that's currently available on the system: Onto ssh!
