"Will 1.4 still work with 0.20 with these patches?" 



Great point Billie.

In 1.5.0, we gave up on compatibility with 0.20 (and early versions of 1.0) 
to make the compatibility requirements simpler; we ended up without 
dependency changes in the hadoop version profiles.  Will 1.4 still work 
with 0.20 with these patches?  If there are dependency changes in the 
profiles, 1.4 would have to be compiled against a hadoop version compatible 
with the running version of hadoop, correct?  We had some trouble in the 
1.5 release process with figuring out how to provide multiple binary 
artifacts (each compiled against a different version of hadoop) for the 
same release.  Just something we should consider before we are in the midst 
of releasing 1.4.4.
