Subject Re: [DISCUSS] Release numbering for stable 2.8 and beyond
Date Sun, 26 Apr 2015 16:51:11 GMT
There are a couple of different approaches we could take. 

How about publishing/releasing bits such as “2.8.0-RC0”. Downstream projects can depend
on these and use them normally similar to the approach that they would have taken with release
2.8.0 or 2.8.0-alpha. After some baking ( or more RC suffixed releases), at some point, a
proper 2.8.0 release could be made? The RC tag clearly indicates to downstream layers that
things will be in flux slightly. Trying to distinguish incompatibilities between 2.8.0 and
2.8.1/2.8.2 ( just because 2.8.0 was tagged alpha in documentation ) are likely to be a nightmare
to deal with especially for new features introduced in the 2.8 release ( which might get changed
slightly based on usage feedback ).

Furthermore, considering the release history of hadoop, the likelihood that 2.9.0 will show
up before 2.8.2 seems to be very high.

With respect to the proposed choice (1), I thought that HBase applied a different approach.
The odd-number releases were always unstable and the even number releases were the stable
ones. This “could" make things a bit more clear for downstream users without needing to
resort to modified versioned numbers ( with alpha/beta tags ) or requiring users to go look
up the website to find out which particular version of 2.8.x was the first stable release.

linux kernel releases. It helps in scenarios where we are forced to downgrade a release, say
due to major issues. We can simply announce it as not stable retroactively, change the pointers
on our website and move on.

I so had to end up calling it alpha outside of the release artifact naming.
