Well, the 'preferred' is the Apache distribution.  Thats what we
should bundle, etc.

That said, I get that you were trying to talk more to our current
predicament where our setup is more involved than it should be for new
users because the 'preferred' Hadoop is a source only distribution and
many will be running other than the Apache distribution anyways.  In
general we need to do work -- documentation, introspecting shims, etc
-- to make it so HBase is more 'universal' and can more easily be
deployed atop any Hadoop whether Cloudera's CDH, newer versions of
Hadoop (hadoop 0.21, 0.22, 0.20s), or vendor X's implementation of
HDFS, Ceph, etc.

I like the idea of linking off to Cloudera doc. -- or any other
vendor's doc -- from ours for install (Todd?).  Or, maybe better would
be linking to a wiki page that vendors can edit as they wish?

Let me ask Dhruba what he thinks about making a 0.20-append release
(He's the release manager).  Will also sound out the hadoop pmc since
they'll have an opinion.
