Jon, what versions of HBase are you asking about? A while back we said that HBase 0.96.0 would be the first release that could assume for a minimum a 1.0.x API [1]. Previous releases we postulated (though probably haven't tested much) could be run on versions as old as branch-0.20-append. We might want to reexamine this "decision" if we we are talking HBase 0.94 (or even HBase 0.92)? +1 on hadoop 1.0 and 2.0 versions/APIs only. I'd be fine w/ a 3.0 snapshot. Any more versions than this and we'll be spending all dev effort on a shim layer that looks like the Pompidou Center to make the various HBase versions run (slowly) over all 57 varieties of Hadoop.
