Pig Installation

Pig Installation

Today we will learn how to install Pig. Installing pig is very simple and straight forward. Following are the steps to install pig. Pig requires Hadoop and java to be already installed.

If you have not installed it, follow the link here

1. Download Pig from Apache Pig website. Check the compatibility of pig you are downloading with already installed hadoop on your machine. I am going to download Pig 0.10.1.

2. After the download is complete, go to download directory and extract Pig 0.10.1.tar.gz

3. Copy the extracted folder in $HOME/pig directory.

4. Edit /etc/bash.bashrc and set PIG_HOME with following command

    sudo leafpad /etc/bash.bashrc

 Then go to last line and copy following

    export PIG_HOME=$HOME/pig

    export PATH=$PATH:PIG_HOME/bin

also set JAVA_HOME if not set earlier using following command. In my case my java is installed at /usr/lib/jvm/java-6-jdk-i386

    export JAVA_HOME=/usr/lib/jvm/java-6-jdk-i386

5. After this close the terminal and open again.

6. Now type pig in terminal and it should open pig shell (grunt)

If it opens then PIG is installed and its ready to use :)
