Hi Danfeng,
I hit this when using an old version of Jython; ensure your Jython version
is 2.5 or newer. In particular, Debian ships with 2.2.1.

* My pig code
Register 'test.py' using jython as myfuncs;
a = load 'a.dat' as (v:chararray);
b = foreach a generate v, myfuncs.helloworld();
dump b;
* test.py
@outputSchema("word:chararray")
def helloworld():
return 'Hello, World'
I wonder what's the problem. My pig version is
pig --version
Apache Pig version 0.8.0-SNAPSHOT (r1085617)
Thanks.
Dan
