Hadoop Single Node 'Cluster' Setup Hadoop Single Node 'Cluster' Setup These instructions will show you how to run Hadoop on a single machine, simulating a cluster by running multiple Java VMs. This setup is great for developing and testing Hadoop applications. The Hadoop website has an excellent tutorial on installing and setting up Hadoop on a single node. This document will supplement that tutorial with some tips and gotchas. You will also write a small sample program that leverages hadoop to fetch titles from web pages. • • Prereqs SSH Client and Server • Berry patch machines: No extra software required. • Mac OSX: You will need to start the SSH server that comes with your Mac.

Open the Control Panel, then click on Sharing, then check the box next to 'Remote Login'. Be sure to turn it off when you are not using Hadoop.

• Windows: • Option 1 (recommended): ssh into a Berry patch machine and work there. If you don't have an SSH client, you will need to.

• Option 2: Install and run Hadoop from the Cygwin command shell. For help please see the tutorial. Java Java 1.5x is required. You may already have it installed; try typing java -version at the command line to see if you have it installed.

It should say version '1.5.x' (e.g., 1.5.0_14). • Berry patch machines: You will need to make sure that you are using the 1.5.x version of Java.

To do so, log into a Berry patch machine and paste this incantation at the command line: echo 'JAVA_HOME=/usr/java/java1.5' >>~/.bashrc && echo 'PATH=/usr/java/java1.5/bin: $PATH' >>~/.bashrc Then log out and back in (or just close and reopen the terminal). • Windows: You want to install the JDK version 5 from.

Don't bother getting the version with NetBeans installed (unless you know what the NetBeans IDE is and want it). The version you want is called something like 'JDK 5.0 Update 14'. • Mac: You already have Java installed. Once Java is installed, go to the command line and type the following command: java -version You should see output similar to this: java version '1.5.0_13' Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-241) Java HotSpot(TM) Client VM (build 1.5.0_13-121, mixed mode, sharing) If you see something to the effect of 'command not found' then Java may not be on your PATH.

If you see a version other than '1.5.x' then you do not have the correct version of Java installed. If you have any trouble with Java installation or otherwise getting your computer set up for use with Hadoop, please ask the TA for help as soon as possible. • Make sure that you have your assigned port numbers for the class (please see the TA if you do not know your port numbers). • Download Hadoop 0.15.2 from an; here is a to one of the mirrors (look carefully at the version number if you pick your own mirror, not all mirrors have the most up-to-date version). • Unpack Hadoop into your home directory. For example: mkdir -p ~/proj/cs147a mv hadoop-0.15.2.tar.gz ~/proj/cs147a tar xvfz hadoop-0.15.2.tar.gz On Windows you will have to enter those commands from a Cygwin shell. • The rest of the instructions assume that you enter commands from the Hadoop root directory.

E.g., if you unpacked to the directory described above, then commands should executed from ~/proj/cs147a/hadoop-0.15.2 • Follow the instructions in the (opens in new window) with the following modifications: • You only need these modifications if you are working on a Berry patch machine. If you are on your personal computer then the Quickstart is fine how it is.

• In hadoop-site.xml You need to change the port numbers 9000 and 9001 to your first two assigned port numbers. • You must set the administration/monitoring port numbers in the configuration file (not described in the quickstart). To do this, you add a few more properties to the site configuration. Your hadoop-site.xml should look something like this (replacing YOURPORTX with one of your assigned ports). Conf/hadoop-site.xml fs.default.name localhost:YOURPORT1 mapred.job.tracker localhost:YOURPORT2 dfs.replication 1 dfs.secondary.info.port YOURPORT3 dfs.info.port YOURPORT4 mapred.job.tracker.info.port YOURPORT5 tasktracker.http.port YOURPORT6 (don't forget to replace YOURPORTX with your assigned port numbers).
