Hi St.Ack. Here is the sense in which the book leads a new user to the route that Mike (and I) took. It seems to say this: <paraphrase> You have a choice. You can download the source for the append branch of hadoop and build it yourself from scratch, which will take who knows how long and require additional tools and may not work on your preferred development platform (see <http://search-hadoop.com/m/8Efvi1EEiaf>, which says "Building sucks"), or you can take this shortcut that seems to work, but has no guarantees. What you cannot do is find a pre-built release of the append branch anywhere for you to just download and use. Your call. </paraphrase> Now, maybe that isn't the message you actually intend. But, to be honest, I think that accurately describes reality, based on the mailing list discussions I've seen. As a user, what I see coming from the HBase project is, "Look! Here's a release!" but it doesn't include all the bits you need and you can't simply go somewhere and fetch those needed bits.

Because the Hadoop project isn't likely to do it, apparently, and, if I understand correctly, HBase is not going to work anytime soon with the next Hadoop release that has append support. So this is not a problem that is going to fix itself. joe
