Hi Jordan, Here is some feedback. I like the proposal and it makes
sense to have such a project as either sub-project or incubator. I
have a few concerns, though:
1- I haven't been following closely the development of the recipes,
but I wonder if it really makes sense to deprecate the current ones in
favor of Curator's, or if it is a better idea to keep multiple
versions in the case of duplicates. People in the community have spent
time on the current recipes, so I don't like very much the idea of
dropping the current recipes without some evidence that the community
accepts it. Note that I'm not saying that deprecating is not the right
thing to do, I'm simply saying that we need to make sure that the
2- The set of committers needs to be more diverse. Perhaps it would be
easier to find more committers if you follow the incubation process,
given that typically people sign up for committership once you post a
proposal there. I wonder how many other people on this list would like
to volunteer to become a committer of Curator, though. I like the
project, but unfortunately I don't have the cycles to do it.
3- If Curator becomes a sub-project of ZooKeeper, then you need at
least one mentor. Is there anyone who would like to sign up to mentor

It would be good to have more diversity here. I would love to
contribute, but I don't feel I have cycles for now.
