             Summary: Register Statements and Param Substitution in Macros
                 Key: PIG-3359
                 URL: https://issues.apache.org/jira/browse/PIG-3359
             Project: Pig
          Issue Type: Bug
          Components: parser
            Reporter: Jonathan Packer
            Assignee: Jonathan Packer


There are some gaps in the functionality of macros that I'll be making a patch 
to address. The goal is to provide everything you'd need to make reusable 
algorithms libraries.

1. You can't register udfs inside a macro
2. Paramater substitutions aren't done inside macros
3. Resources (including macros) should not be redundantly acquired if they are 
already present.

Rohini's patch https://issues.apache.org/jira/browse/PIG-3204 should address 
problem 3 where Pig reparses everything every time it reads a line, but there 
still would be a problem if two separate files import the same macro / udf 
file.
