Joep Rottinghuis commented on PIG-2277:
---------------------------------------
@Daniel: at the moment it is an either-or proposition between 22 and 20.2 due
to the project split and the API changes.
Pig relies on a single hadoop-core jar or a set of jars (due to the project
split).
The API changes could possibly be shimmed in with additional effort.
At the moment I would not recommend to apply the patch to Pig 0.8 in SVN until
Hadoop 22 is released.
People that want to build against 22 can apply the patch themselves and build
against 22.
> Make Pig compile against Hadoop 0.22

> Currently Pig depends on hadoop 0.20.
> While it is relatively easy to pass a property to the build (through -D or
> through build.properties) to set hadoop-core.version to something else, the
> problem is that since hadoop 0.22 the project has been split.
> No longer is there one single hadoop-core jar to build against.
