When I run a mapreduce job using hadoop command, I use -libjars to setup my jar to the cache and the classpath. How to do something like this in PIG?

Answer 1

An extension to zsxwing's answer.
You can also specify multiple jar paths as

pig -Dpig.additional.jars="/local/path/1/*:/local/path/2/*"

Answer 2

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.

register /local/path/to/myJar.jar
