The google doc has been looked at by quite a few guys, I think. I'm about to create some more jiras around abstracting ZooKeeper, and would really appreciate if someone has specific comments on the section of document outlining the steps to abstract ZK - to check some important pieces aren't forgo

For future reference, attachments are filtered out by the list serve. For working drafts, we've had success using a shared editing service (Google Docs, specifically). Best to attach later-stage docs to JIRAs. On Thu, Apr 17, 2014 at 9:29 PM, Mikhail Antonov wrote: > Guys, > > attached is a rewo

Hi Cos, Thanks for providing this overview, and more importantly, considering these contributions. Reading through the relevant JIRAs, looks to me like HBase will be in a better position than before to have this abstraction in place, provided the changes are fully completed. Thanks again for the

Bringing consensus based strong consistency into HBase

2014-04-07 Thread Konstantin Boudnik
Guys, As some of you might have noticed there is a number of new JIRAs opened recently that are aiming on abstracting and separating ZK out of HBase guts and making it an implementation detail, rather than a center of attention for some parts of the HBase. I would like to send around a short docu
