Re: Replacing string in input parameter
Take a look at http://pig.apache.org/docs/r0.10.0/cont.html#Parameter-Sub-
Specifying Parameters Using the Declare Statement.

You can do this in your case
%declare page_input_path `echo $input_path | sed 's/output/output\/page/g'`

Or you can use embedded python (
http://pig.apache.org/docs/r0.10.0/cont.html#embed-python) to bind the
input and output after manipulating the parameters using python.
