Published On Database management system is necessary every where whether it’s a web application or other business purpose software;in ubuntu 10.04 you may like to use MySQL,the fastest database management system for web applications. MySQL is one of the most widely used database management system and it is light,free and open source so it is also in resonance with ubuntu philosophy.The aim of this post is to help you in installing mysql on your ubuntu 10.04 to help you in getting started with mysql.
Note: for the 1.0.x series of Hadoop the following articles will probably be easiest to follow: The below instructions are primarily for the 0.2x series of Hadoop. Hadoop can be downloaded from one of the Apache download mirrors . You may also download a nightly build or check out the code from subversion and build it with Ant .
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.
Overview Requirements Unix and Windows users need the following: Hadoop 20 - http://hadoop.apache.org/core/ Java 1.6 - http://java.sun.com/javase/downloads/index.jsp Set JAVA_HOME to the root of your Java installation. Ant 1.7 - (optional, for builds) http://ant.apache.org/ JUnit 4.5 - (optional, for unit tests) http://junit.sourceforge.net/ Windows users need to install Cygwin and the Perl package: http://www.cygwin.com/
Overview The Pig tutorial shows you how to run two Pig scripts in local mode and mapreduce mode. Local Mode : To run the scripts in local mode, no Hadoop or HDFS installation is required. All files are installed and run from your local host and file system. Mapreduce Mode : To run the scripts in mapreduce mode, you need access to a Hadoop cluster and HDFS installation. The Pig tutorial file (tutorial/pigtutorial.tar.gz file in the pig distribution) includes the Pig JAR file (pig.jar) and the tutorial files (tutorial.jar, Pigs scripts, log files).
Let's run the same script on your cluster that we ran in the local mode example Example 2.1, “Running Pig in Local Mode” . If you are running on a Hadoop cluster you have never used before you will most likely need to create a home directory. Pig can do this for you:
The screenshots in this tutorial use Ubuntu 12.04, but the same principles apply also to Ubuntu 12.10, 11.10, 10.04, and any future version of Ubuntu . Actually, you can install pretty much any Linux distribution this way. Introduction VirtualBox allows you to run an entire operating system inside another operating system. Please be aware that you should have a minimum of 512 MB of RAM . 1 GB of RAM or more is recommended. Comparison to Dual-Boot Many websites (including the one you're reading) have tutorials on setting up dual-boots between Windows and Ubuntu.
April 9th, 2008 This is the scenario that you run Windows as your host operating system and Ubuntu in a VirtualBox, and that you want to access a specific Windows folder from Ubuntu. First you have to make sure that have install Guest Additions . From the VirtualBox's menu go to Devices → Install Guest Additions... This will mount a virtual CD on your /media/cdrom . Normally this folder's window will show up.
Notes Installing Ubuntu Notes This tutorial goes over the option of installing a traditional dual-boot. If there is any chance you might want to remove Ubuntu and return to Windows exclusively, do not set up a traditional dual-boot. Instead, I would recommend you start migrating to open source Windows applications in Windows, playing around with Ubuntu virtually inside Windows , and then use a dual-boot between Ubuntu and Windows. If you are using Mac OS X, the community documentation may help you out here.
This simple tutorial shows you how to login as root (administration) in Ubuntu 11.04 Natty. Even though it’s not recommended to logon to Ubuntu as the administrator, you still have the option to do so if you wish. One big reason why most Linux distributions won’t allow the root user to login is that, root or administrator has complete control of the system. Any small mistake might have huge impact on the stability of your system. So to prevent this, the root account is disabled by default.
Command Line If you've installed Apache Ant as described in the Installing Ant section, running Ant from the command-line is simple: just type ant . When no arguments are specified, Ant looks for a build.xml file in the current directory and, if found, uses that file as the build file and runs the target specified in the default attribute of the <project> tag. To make Ant use a build file other than build.xml , use the command-line option , where file is the name of the build file you want to use (or a directory containing a build.xml file). If you use the option, Ant will search for a build file first in the current directory, then in the parent directory, and so on, until either a build file is found or the root of the filesystem has been reached.
I am using Ubuntu Linux 9.04. JDK is located in “/usr/lib/jvm/java-6-sun” and ANT is located in “/usr/share/ant” in my machine. Following instruction shows instruction for configuration. If you don’t know JAVA_HOME, you can retrieve with command “sudo update-alternatives –config java” as following. xxx@xxx-desktop:~$ sudo update-alternatives --config java There is only 1 program which provides java (/usr/lib/jvm/java-6-sun/jre/bin/java). Nothing to configure.
Home > Apache Ant , Ubuntu > Installing ANT on Ubuntu Hi All, Installing ANT on Ubuntu is fairly very simple. All We have to do is to open the terminal window. And simply run the below command.
