Subject [jira] [Commented] (MRUNIT-56) 0.8.0 release does not work with Hadoop 0.23
Date Wed, 08 Feb 2012 00:23:03 GMT

    [ https://issues.apache.org/jira/browse/MRUNIT-56?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13203017#comment-13203017
] 

Alejandro Abdelnur commented on MRUNIT-56:
------------------------------------------

I'd suggest we publish 2 different versions for the same groupId/artifact, with the version
of hadoop encoded in the version. By doing this users will get Maven to do dependency version
resolution, otherwise for Maven the JARs would be for different entities and you could potentially
end up with the 2 JARs in your project.
