Johnny Zhang commented on PIG-3153:
-----------------------------------
please note in javascript, I use the x:{t:(word:chararray,num:long)} to define
the return schema, which uses a bag to wrapper a tuple. This is the same as
test testPythonAbsolutePath() did.
I tried to define the schema as t:(word:chararray,num:long), but didn't
successfully to load the data into it correctly in 8 line of the javascript. I
think this might be the case to all javascript. will look further.
