Owen O'Malley updated PIG-924: ------------------------------ Status: Open (was: Patch Available) -1 I think this is a bad idea and is totally unmaintainable. In particular, the HadoopShim interface is very specific to the changes in those particular versions. We are trying to stabilize the FileSystem and Map/Reduce interfaces to avoid these problems and that is a much better solution. > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
