There are two ways to add external jars to Pig environment.

  1. Use "-Dpig.additional.jars" to start Pig

    pig -Dpig.additional.jars=/local/path/to/your.jar

  2. Use "register" command in Pig scripts or grunt

    register /local/path/to/your.jar;

You can use any one according to your requirement.
