Apache Pig can be downloaded from http://pig.apache.org
Download the latest release from its website
Unzip the downloaded tar file
Set the environment variables in your system as
export PIG_HOME="/home/hadoop/software/pig-0.9.2"
export PATH=$PATH:$PIG_HOME/bin
Set the place where you downloaded pig and also set its path
If you plan to run Pig on hadoop cluster then one additional variable needs to be set
export PIG_CLASSPATH="/home/hadoop/software/hadoop-1.0.1/conf"
It tells about the place where to look for hdfs-site.xml and other configuration files for hadoop
Restart your computer
Thats it , now lets test the installation
On the command prompt
type
# pig -h
it shoud show the help related to Pig , and its various commands.
Done :) ,
Next you can read about
How to run your first Pig script in local mode
Or about various Pig running modes
many thanks
