- Change "Working directory" into your PIG_HOME
- In Classpath, add user entries "$PIG_HOME/build/classes" and "$PIG_HOME/pig*.jar"
Troubleshooting
- Build problems: Check if eclipse is using JDK version 1.6, pig needs it (Under Preferences/Java/Compiler).
- If you encounter this error: Missing required library: 'build/ivy/lib/Pig/javacc-4.2.jar' try one of the solutions described in PIG-3399.
