In this Post, we will be using (Ubuntu 13.10) image to setup our LXC for multi host Hadoop cluster setup. Below is the Environment used to setup LXC.

VIRTUAL MACHINE RAM 1024MB (3 GB Recommended)
USER/PASSWORD User/password

Minimum System Requirement:

HDD Space: 80 GB

RAM: 3-4 G.B Per Box

O.S: Windows 7 (Native)

Software Installed On Each P.C:

Vmware Player

What is LXC?

One of the light weight virtualization solution. It provides benefit of faster startup with less memory overheads. LXC containers occupy very little disk space and filesystem of containers are independently stored in the native operating systems filesystem.

Following are the set of steps you need to follow to have LXC and required Node setup.

Step 1: Launch Ubuntu 13.10 and launch Terminal.

Step 2: Change user to root.

Step 3: Download and update Ubuntu packages.

Step 4: Install LXC

Step 5: Create LXC Container.

Step 7: Install LXC Web for Administration (Web Application to simplify administration).

Step 8: Launch Web Console.

Enter default User ID and password (admin/admin). Once you enter you get an admin console with various tabs. Check the status of the container you created using command line in previous step. If it’s not running, click on ‘start’ to run.

(Remember if it’s the first time you are running after creating your first container, reboot the system by click on red color reboot button and try starting again. You will find your container starts without any problem).

Step 9: Reboot the System.

Step 10: Start LXC Container (if already started start button will be disabled). You can use stop and freeze if required.

For Example if we create more containers we can start them by using the appropriate start button as specified below.

Ensure after you click on the start button it changes the status and marks the container running as specified below.

Step 11: Check the status of the container by using command line as specified below by using #lxc-ls –fancy command.

Step 13: Install essential package in the container(s). We can create one container, install all essential packages and software and later we can clone it to create other containers. Below command assumes that you have created the container named myConatiner2, started the container from the webconsole and have launched a console attached to the container. You can do this by using commands.

#lxc-create –t Ubuntu –n myconatiner2
Start it from web console as specified in step-9

#lxc-attach –n mycontainer2

Once you get the console attached use command as specified below.

Press Y to complete the Installation. Once installed you get the prompt back as specified in the below screen.

Now mycontainer2 has the installed the set of common software from the repository and its up-to-date. It’s time to prepare your container to have Java. Install java as specified in the next step.

Step 14: Install Java on Container.

This command starts fetching and installing Java (openjdk) which will be required to setup Hadoop processes. Once the installation is done confirm installation using Javac and Java commands as specified below.

Once Java is installed we need to get the Hadoop distribution for which we will be using wget utility. Next step will tell you how to install wget utility.

Step 15: Install wget utility on Container.

Step 16: Download and extract Hadoop 1.2.1

Using wget fetch Hadoop 1.2.1 as specified below, ensure no mistakes are made in typing the url. Before using wget ensure you create a directory (Hadoop) and move in the directory to get the downloaded Hadoop binary in the current folder.

Once Downloaded extract it using tar command specified below.

Navigate in the extracted directory to ensure you have conf, bin and other folders to configure Hadoop.

Now we have a container with Java and Hadoop libraries installed. We have to clone (depending on the number of nodes you want to have in your cluster).

Step 17: Clone to have required number of Containers.

We have to repeat this step, depending on the number of containers we want to have in our cluster. Once nodes (containers ) are created, each will have its unique IP and resource directories which we can use to implement our LAB: 01 (for complete course ware mail to

Stop the container from webui as specified before you clone.

Clone the container to have any number of clones you need and start the containers again by clicking on the start button of the specified containers.

Ensure all the containers you want are in running state.

Step 18: List and Verify Containers Status and IP Address.

Use #lxc-ls –fancy to list the details of the containers created.

Once all these steps are followed and you get the desired result.
