But, since that some users may already have their production system on HBase-2.0.x, maybe we should consider their feelings, they are the 'first movers'. If we retire branch-2.0 so quickly, IIRC, the branch-2.0 will be the shortest life branch ever. I think it will hurt the feeling of those 'first movers'. If we take this into count, then I think maybe we should keep branch-2.0 at least one year. If the community is shorthanded, I volunteer to take responsible to decide/backport/release branch-2.0 since I was working on this branch most recently. Anyway, this thread is about releasing HBase2.2.x, I will vote a +1 for it, as for HBase-2.0.x, we can discuss later. Best Regards Allan Yang
