================================================================================
From what I have been able to see in the archives the most common cause of this error seems to be that jython.jar is not in the classpath; I've checked and mine is in the classpath. I have the full path to both jython.jar and test.py in the pig script. Are there other causes that might produce this error? Python is in /usr/local/bin rather than /usr/bin; would that produce this, and if so how would I address the error?
Thanks,Andrea Leistra
