Subject Re: [DISCUSSION] Release process
Date Thu, 01 Apr 2010 17:36:56 GMT
Thanks Tom and Owen for stepping up --

We're using 0.20.2 as effectively 1.0 here, too, so I think a 1.0 branch is
a good idea that recognizes that status quo and deal with it, particularly
for having a 1.0 that's pre-split and pre-security (big changes).

Couple random thoughts:

1)  I agree with marking the old API stable in 1.0, especially considering
hive/pig/etc all use it..  what do we do with the new API?  Mark it
"next-gen"?  We have one random job that uses it and I bet that's the same
for a lot of people.  Leaving it there would be useful as far as not
breaking existing code and allowing the frameworks to port over to the new
API slowly and not have to maintain 2 branches.. but then that starts to
obligate us to fully support the new API on the 1.0 branch.

2)  Does this come with a date for 2.0?  Will there be a 1.9 or maybe a
2.0-alpha? I think it might be wise to try and deploy an alpha-2.0 branch a
few places before making a firm commitment to "this is THE 2.0 API and
directory layout".

3)  What about append?  Based on the amount of work that went into it, I'm
assuming it's a very difficult backport..  does this mean 1.0 will never
support append?  (if it can't, it can't).
