Yeah, DoA is harsh, when I meant more like "abandoned at release". Similar to 0.21. Well that is my question, really. Is it? We've heard that CDH4 is going to be start from something a lot closer to 0.23 than 0.22, that Hortonworks is committed to 0.23. It seems 0.23 is the future, and a RC may be happening as early as the end of this year, i.e. in the next month or so. Given recent history and the above described commitments, I think there is confusion about where/if 0.22 fits in. People will work on what inspires them, but it seems the center of gravity has already moved beyond 0.22. Is that a fair statement? > The facts that I have are such that there will be a reasonably large > deployment of Hadoop 0.22 and HBase at EBay makes me believe that such > a combination should be of interest to HBase community. Then I'm sure the eBay guys will have that interest. :-) Best regards, - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White) ----- Original Message ----- > From: Roman Shaposhnik <[email protected]> > To: [email protected]; Andrew Purtell <[email protected]>; Konstantin > Shvachko <[email protected]> > Cc: Konstantin Boudnik <[email protected]> > Sent: Tuesday, November 1, 2011 2:16 PM > Subject: Re: proper pace for JIRA integration > > On Tue, Nov 1, 2011 at 1:00 PM, Andrew Purtell <[email protected]> > wrote: >>> There will be some deployment of .22 in big shops as far as I know. >> >> Who are these "big shops"? > > EBay is a good example here I'm CCing Konstantin if you want to find > out more details. > >> AFAIK, compared to 0.20.x or 0.23, 0.22 has a number of regressions. > > I'm NOT sure I agree as far as 0.23 goes.
