Thinking ahead to hadoop-2.7
Folks,
With hadoop-2.6 out it's time to think ahead.
As we've discussed in the past, 2.6 was the last release which supports JDK6.
I'm thinking it's best to try get 2.7 out in a few weeks (maybe by the
holidays) with just the switch to JDK7 (HADOOP-10530) and possibly
support for JDK-1.8 (as a runtime) via HADOOP-11090.
This way we can start with the stable base of 2.6 and switch over to
JDK7 to allow our downstream projects to use either for a short time
(hadoop-2.6 or hadoop-2.7).
I'll update the Roadmap wiki accordingly.
Thoughts?
thanks,
Arun

If there are not a lot of changes just to make Java 7 a requirement (I
understand it's basically pom changes and unit test failure and findbugs
fallouts), how about merging that with the next release and declare the
next release and on Java-7-only?

I don't think so —the 2.6 release was tested pretty aggressively on JDK7,
and solely on it for Windows. Pushing out a 2.7 release would be more
symbolic than of use to people
there's one exception: the fix for java 8 security. I do also think there
may be Java 8 test failures; these need to be identified and fixed ...
which would point more to a 2.8 release for that

That's a good point. I think it's important to point out that most of
our users are already on JDK7. We shouldn't think of this decision as
adding support for something new, we should think about it as taking
something away (JDK6 support). I think it's good that we are finally
moving away from supporting JDK6, but I'm not completely sure that we
need to devote a whole release to that. Are there a lot of open JDK7
issues that would require a release to straighten out?

That's a good point. I think it's important to point out that most of
our users are already on JDK7. We shouldn't think of this decision as
adding support for something new, we should think about it as taking
something away (JDK6 support). I think it's good that we are finally
moving away from supporting JDK6, but I'm not completely sure that we
need to devote a whole release to that. Are there a lot of open JDK7
issues that would require a release to straighten out?
best,
Colin

It would be nice to cut the branch for the next "feature" release (not just
Java 7) in the first week of January, so we can get the RC out by the end
of the month?
Yesterday, this came up in an offline discussion on ATS. Given people can
run 2.6 on Java 7, is there merit to doing 2.7 with the exact same bits
targeting Java 7? I am okay with going through with it, as long as it
doesn't delay the next feature release.

Re: Thinking ahead to hadoop-2.7
Posted by Sangjin Lee <sj...@gmail.com>.
If 2.7 is being positioned as the JDK7-only release, then it would be good
to know how 2.8 lines up in terms of timing. Our interest is landing the
shared cache feature (YARN-1492)... Thanks.

Thanks for starting this thread, Arun.
Your proposal seems reasonable to me. I suppose we would like new features
and improvements to go into 2.8 then? If yes, what time frame are we
looking at for 2.8? Looking at YARN, it would be nice to get a release with
shared-cache and a stable version of reservation work. I believe they are
well under way and should be ready in a few weeks.
Regarding 2.7 release specifics, do you plan to create a branch off of
current branch-2.6 and update all issues marked fixed for 2.7 to be fixed
for 2.8?
Thanks
