Re: [DISCUSS] move hedwig/bookkeeper to subproject
I tend to agree that we should do one at a time, and it is fine with  
me to have bookkeeper going out first.

On the discussion of Incubator vs. ZK sub-project, I don't see much  
different except for the PMC. If I understand the incubator scheme  
correctly, they have one PMC responsible for the oversight of  
incubator projects. Since we know the ZooKeeper PMC well and some of  
us are actually members of it, it seems more natural to me to stick  
with the ZK PMC instead of moving to a different PMC. Consequently, my  
current preference is ZK sub-project. Pat also pointed out that the ZK  
umbrella is broad enough to accommodate BK/Hedwig according to the  
Apache board resolution that established the project.
