It's hard to discuss something when you don't see anything.
The best way is:
1. publish your pig script.
2. publish the whole stacktrace. you can go directly to tasktracker node
and grab log output from failed task.
3. check input path for your pig script. Maybe you do provide wrong input
path and schema is incompatible.
4. check libraries in classpath. It's possible that you have problem with
classloader or you miss some jar files or thier version is incompatible.
