hbase-2600 should go in when its ready. It might make 0.94. Its ok if it doesn't I'd say. We need to tread carefully regards 2600 (Alex is on it. He was here Tuesday. We talked of making a 2600 branch w/ his current work and in which we'd work through bugs and migration). If you want to facilitate CDH4 carrying 0.94, I'd say 2600 goes into 0.96 because it'll require migration effort by Clouderians hacking up a migration script that runs the 0.90->0.92 .META. rewrite followed by the 2600 .META. rewrite. I say 'by Clouderians' because as I say above, I don't think we should be in the business of testing and verifying what happens if you skip versions upgrading. I'd be fine pushing out 2600. CDHs hang around a while. Having to answer 0.92 questions when the rest of us are 0.94'ing or 0.96ing would be a pain. St.Ack
