Re: [DISCUSS] Hadoop SSO/Token Server Components
Hi Larry (and all),

Happy Fourth of July to you and yours.

In our shop Kai and Tianyou are already doing the coding, so I'd defer to
them on the detailed points.

My concern here is there may have been a misinterpretation or lack of
consensus on what is meant by "clean slate". Hopefully that can be quickly
cleared up. Certainly we did not mean ignore all that came before. The idea
was to reset discussions to find common ground and new direction where we
are working together, not in conflict, on an agreed upon set of design
points and tasks. There's been a lot of good discussion and design
preceeding that we should figure out how to port over. Nowhere in this
picture are self appointed "master JIRAs" and such, which have been
disappointing to see crop up, we should be collaboratively coding not
planting flags.

I read Kai's latest document as something approaching today's consensus (or
at least a common point of view?) rather than a historical document.
Perhaps he and it can be given equal share of the consideration.
