Jonathan Coveney commented on PIG-2939:
---------------------------------------
I think that we could instead add scope to Pig (the beloved {}'s), which would
give this for free.
> Pig macros need namespaces to avoid namespace collisions facilitate macro
> sharing

> Key: PIG-2939
> URL: https://issues.apache.org/jira/browse/PIG-2939
> Project: Pig
> Issue Type: New Feature
> Components: parser, piggybank
> Affects Versions: 0.11
> Environment: All
> Reporter: Russell Jurney
> Assignee: Daniel Dai
> Fix For: 0.11
>
>
> With sharing macros, colliding namespaces is very likely given that multiple
> macros from different authors might import them in the same pig script. I
> propose that we add namespaces to macros.
> We can either add a namespace command in macros, or name the space by the
> filename.
> This ticket is needed to facilitate sharing of macros within and between
> organizations and individuals in piggybank or on github or wherever.
