Subject Re: RTC vs CTR (was: Concerning Sentry...)
Date Wed, 25 Nov 2015 18:44:06 GMT
Most of the Hadoop ecosystem uses RTC. I can't speak to other projects but
on the one I chair there's no conspiracy to exclude anyone.

I chair Bigtop. We recently tested a switch to CTR. It went very well and
so we just wrapped up a vote to make it the permanent state of affairs. I
think this is the best option for Bigtop, which has a small but active
group of committers each working in loosely coupled ways on different parts
of the tree. I also chair HBase. We were spun out of Hadoop direct to TLP
and inherited the RTC ethic from our parent community. I did recently test
the state of consensus on RTC vs CTR there and it still holds. I think this
model makes sense for HBase, which is a mature (read: complex) code base
that implements a distributed database. For sure we want multiple sets of
eyes on changes there. They can have unexpected consequences. Almost above
all, we want to do due diligence on not introducing bugs that lose user
data.

So, to each their own? Please.
