Running Hadoop On Ubuntu Linux Single Node ClusterIn 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. Google File System GFS and of the. Map. Reduce computing paradigm.

How To Install Cpan Modules Without Internet Access on this page. It provides high throughput access to. The main goal of this tutorial is to get a simple Hadoop installation up and running so that you can play around with. This tutorial has been tested with the following software versions Ubuntu Linux 1. LTS deprecated 8. LTS, 8. 0. 4, 7. 1. Hadoop 1. 0. 3, released May 2. Figure 1 Cluster of machines running Hadoop at Yahoo Source Yahoo. Prerequisites. Sun Java 6. Hadoop requires a working Java 1. Java 5 installation. However, using. Java 1. Java 6 is recommended for running Hadoop. For the. sake of this tutorial, I will therefore describe the installation of Java 1. Important Note The apt instructions below are taken from this Super. User. com thread. I got notified that the previous instructions that I provided no longer work. Please be aware that adding a third party repository to your Ubuntu configuration is considered a security risk. If you do not want to proceed with the apt instructions below, feel free to install Sun JDK 6 via alternative means e. Oracle and then continue with the next section in the tutorial. Add the Ferramosca Robertos repository to your apt repositories See https launchpad. Update the source list sudo apt get update. Install Sun Java 6 JDK sudo apt get install sun java. Select Suns Java as the default on your machine. See sudo update alternatives config java for more information. The full JDK which will be placed in usrlibjvmjava 6 sun well, this directory is actually a symlink on. Ubuntu. After installation, make a quick check whether Suns JDK is correctly set up 1.

Configuring SSHHadoop requires SSH access to manage its nodes, i. Hadoop. on it which is what we want to do in this short tutorial. For our single node setup of Hadoop, we therefore need to. SSH access to localhost for the hduser user we created in the previous section. I assume that you have SSH up and running on your machine and configured it to allow SSH public key authentication. If. not, there are several online guides available. First, we have to generate an SSH key for the hduser user. P. Generating publicprivate rsa key pair.

Generally, using an empty password is not. Hadoop interacts with its nodes. Second, you have to enable SSH access to your local machine with this newly created key. HOME. sshidrsa. HOME. The final step is to test the SSH setup by connecting to your local machine with the hduser user. The step is. also needed to save your local machines host key fingerprint to the hduser users knownhosts file.

Check the SSH server configuration in etcsshsshdconfig, in particular the options Pubkey. Authentication. which should be set to yes and Allow.

Disabling IPv. 6One problem with IPv. Ubuntu is that using 0. Hadoop configuration. Hadoop binding to the IPv. Ubuntu box. In my case, I realized that theres. IPv. 6 on a box when you are not connected to any IPv. Hence, I simply. disabled IPv. Ubuntu machine. Your mileage may vary. To disable IPv. 6 on Ubuntu 1. LTS, open etcsysctl. You have to reboot your machine in order to make the changes take effect. You can check whether IPv. A return value of 0 means IPv. Alternative. You can also disable IPv. Hadoop as documented in.

If you have LZO compression enabled in your Hadoop cluster and compress job outputs with LZOP not covered in this tutorial Conveniently inspect an LZOP compressed file from the command line run via lzohead hdfspathtolzopcompressedfile. Requires installed lzop command. Add Hadoop bin directory to PATHexport PATHPATH HADOOPHOMEbin. You can repeat this exercise also for other users who want to use Hadoop. Excursus Hadoop Distributed File System HDFSBefore we continue let us briefly learn a bit more about Hadoops distributed file system. The Hadoop Distributed File System HDFS is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. HDFS is highly fault tolerant and is designed to be deployed on low cost hardware. HDFS provides high throughput access to application data and is suitable for applications that have large data sets. HDFS relaxes a few POSIX requirements to enable streaming access to file system data. HDFS was originally built as infrastructure for the Apache Nutch web search engine project. HDFS is part of the Apache Hadoop project, which is part of the Apache Lucene project. The Hadoop Distributed File System Architecture and Designhadoop.
