Subject [jira] Commented: (PIG-924) Make Pig work with multiple versions of Hadoop
Date Thu, 20 Aug 2009 18:33:15 GMT

    [ https://issues.apache.org/jira/browse/PIG-924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745551#action_12745551

Todd Lipcon commented on PIG-924:
---------------------------------

Hey guys,

As we understood it, Pig 0.5 wasn't due for quite some time. If it's the case that 0.5 is
a small release on top of 0.4 and it should be out in a few weeks, this seems a lot more reasonable.

Most likely we'll end up applying this patch to the 0.4 release for our distribution, even
if there are multiple branches made in SVN. That's fine, though - we've got a process developed
for this and are happy to support users on both versions for the next several months as people
transition to 0.20 and the new APIs.

Feel free to resolve as wontfix
-Todd

> 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.
