Introduction

This Vagrant project creates a VM with single node setup of Hadoop v2.3.0 with YARN installed.

Getting Started

1. Download and install VirtualBox
2. Download and install Vagrant.
3. Run vagrant box add centos65 https://github.com/2creatives/vagrant-centos/releases/download/v6.5.1/centos65-x86_64-20131205.box
4. Git clone this project, and change directory (cd) into this project (directory).
5. Run vagrant up to create the VM.
6. Run vagrant ssh to get into your VM.
7. Run vagrant destroy when you want to destroy and get rid of the VM.

Some gotcha's.

1. Make sure you download Vagrant v1.4.3 or higher.
2. Make sure when you clone this project, you preserve the Unix/OSX end-of-line (EOL) characters. The scripts will fail with Windows EOL characters.
3. Make sure you have 8Gb of free memory for the VM. You may change the Vagrantfile to specify smaller memory requirements.
4. This project has NOT been tested with the VMWare provider for Vagrant.
5. You may change the script (setup.sh) to point to a different location for Hadoop to be downloaded from. Here is a list of mirrors: http://www.apache.org/dyn/closer.cgi/hadoop/common/.

Make the VM setup faster

You can make the VM setup even faster if you pre-download the Hadoop and Oracle JDK into the /resources directory.

1. /resources/hadoop-2.3.0.tar.gz
2. /resources/jdk-7u51-linux-x64.gz

The setup script will automatically detect if these files (with precisely the same names) exist and use them instead. If you are using slightly different versions, you will have to modify the script accordingly.

Web UI

You can check the following URLs to monitor the Hadoop daemons.

1. [NameNode] (http://localhost:50070/dfshealth.html)
2. [DataNode] (http://localhost:50075/dataNodeHome.jsp)
3. [ResourceManager] (http://localhost:8088/cluster)
4. [NodeManager] (http://localhost:8042/node)
5. [JobHistory] (http://localhost:19888/jobhistory)

Note that you point your browser to "localhost" because when the VM is created, it is specified to perform port forwarding from your desktop to the VM.

Vagrant boxes

A list of available Vagrant boxes is shown at http://www.vagrantbox.es.

Vagrant box location

The Vagrant box is downloaded to the ~/.vagrant.d/boxes directory. On Windows, this is C:/Users/{your-username}/.vagrant.d/boxes.
