Apache Pig itself very easy to install but you must have Apache Hadoop and Java installed on the instance. In other words, you can follow our guide on installing Apache Hadoop and Java from previous guide to further proceed.
Download Pig latest version (at the time of writing this tutorial pig-0.17.0 is the latest) from official website. You will wget pig-0.17.0.tar.gz file. We will keep Pig in /usr/local/pig location. That is actually installation. Now run these :

tar -xzf pig-0.17.0.tar.gz sudo mv pig-0.17.0 /usr/local/pig |

nano ~/.bashrc |
Add PIG_HOME and PIG_CLASSPATH path to it :

export PIG_HOME=/usr/local/pig export PATH=$PATH:$PIG_HOME/bin |
