Arun C Murthy commented on PIG-924:
-----------------------------------

I agree with Owen.

One conceivable option is for the Pig project to maintain separate branches 
(per Pig release) to support the various Hadoop versions... several projects 
are run this way. Clearly it adds to the cost for pushing out a release for the 
Pig committers and it is their call.

> The current Pig build scripts package hadoop and other dependencies into the 
> pig.jar file.
> This means that if users upgrade Hadoop, they also need to upgrade Pig.
> Pig has relatively few dependencies on Hadoop interfaces that changed between 
> 18, 19, and 20.  It is possibly to write a dynamic shim that allows Pig to 
> use the correct calls for any of the above versions of Hadoop. Unfortunately, 
> the building process precludes us from the ability to do this at runtime, and 
> forces an unnecessary Pig rebuild even if dynamic shims are created.
