Bug in Schema comparison for equality
-------------------------------------
Key: PIG-666
URL: https://issues.apache.org/jira/browse/PIG-666
Project: Pig
Issue Type: Bug
Components: build
Environment: i686 i386 GNU/Linux
Reporter: Araceli Henley
Priority: Minor
Santhosh is currently improving Error Handling, I ran these tests against :
pig_phase_3.jar
This is a bug in the schema comparison for equality
