> Make Pig work with multiple versions of Hadoop
> Key: PIG-924
> URL: https://issues.apache.org/jira/browse/PIG-924
> Project: Pig
> Issue Type: Bug
> Reporter: Dmitriy V. Ryaboy
> Attachments: pig_924.2.patch, pig_924.3.patch, pig_924.patch
> 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.
