Subject [jira] [Commented] (MRUNIT-56) 0.8.0 release does not work with Hadoop 0.23
Date Sat, 04 Feb 2012 18:07:53 GMT

    [ https://issues.apache.org/jira/browse/MRUNIT-56?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13200483#comment-13200483
] 

Brock Noland commented on MRUNIT-56:
------------------------------------

I could be wrong, but the code itself works with both versions but the jar we distribute only
works with the version we compiled against.

>From a tarball perspective, we could provide a single tar with two jars inside.  WIth
maven, I guess users could select mrunit-0.8.0 or mrunit-0.8.0-hadoop-0.20?
