"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.
