how to call a pig script within another pig script

Question

I have a file in hdfs with 100 columns, which i want to proces using pig. I want to load this file into a tuple with columns names in a separate pig script, and reuse this script from other pig scripts. How do I do this?

Say this 100 column pig script is - 100col.pig. How do i call it from anotherone.pig?

Answer 1

Check into the exec command (for batch processing) or the run command (for interactive scripts). Also, if you need to use (non-grunt) shell commands, check the fs command. Here's a good reference:

You should try using macros that is present in pig version 0.9.
