Tom White 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.
That's correct.
> 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?
That's probably the best solution. How about mrunit-0.8.0 and
mrunit-hadoop1-0.8.0 for the names?
> 0.8.0 release does not work with Hadoop 0.23
