Subject [DISCUSSION] Release Plan for Apache Hadoop 2.6.4
Date Wed, 06 Jan 2016 23:59:23 GMT
Hello folks,
       Hope everyone had a wonderful holiday and good rest in passed weeks. We just had a
2.6.3 release on Dec.17 and now it is a good time to look forward to the next branch-2.6 maintenance
release - 2.6.4 in the beginning of new year. As usual, this release will be based on latest
release 2.6.3 but include a couple of critical/blocker bug fixes that identified in community

Things Done/TODO:

  + Schedule
    -- According to previous email discussion thread in community, we are prefering fast-moving
way (roughly as monthly) of releasing fixes on branch-2.6. So I would expect this release
could happen around end of Jan. or early of Feb. dependens on if RC & VOTE process going
on smoothly. Also, it should be after release 2.7.2 to get rid of any possible disturb to
that release.

  + Branch
    -- 2.6.4 will be based on branch-2.6, which has been open to 2.6.4 commits for a while.
I plan to branch out branch-2.6.4 sometime next week according to status of target/fixed fixes.
    -- Before 2.6.4 branch is cut off, new commits coming as fix to 2.6.4 is good to commit/merge
to trunk, branch-2 and branch-2.6.

  + Patches
    -- In last couple of days, I went through all critial/blocker bug fixes in the coming
2.7.2 release and ping authors/committers on JIRA to ask for the same effort on branch-2.6.4.
I could do more rounds of the same practice in case I could miss something helpful. Also,
a kindly reminder from original author and committer is also appreciated.
    -- So far, 2.6.4 already has 18 fixes as list of [1] shows. However, there are totally
55 fixes target for 2.6.4 for now [2], so there is still a large gap and we need to work harder
to resolve these tickets as many as we can and push out some non-critical ones to meet our
promise of date.

  + Release
    -- Still too early to do anything directly related to RC. Will work on resolve fixes in
list of [2] first, and appreciate any help on this effort.

Any thoughts? Especially on schedule and list of patches that should be included?

Subject: [RESULT] [VOTE] Release Apache Hadoop 2.6.3 RC0

Hi all in community,
     I give my binding +1 to close the vote for 2.6.3 RC0. With 18 +1s (10 binding), one +0
(non-binding) and no -1s, the vote passes.

Thanks for everyone who tried the release candidate and voted. Thanks Vinod, Sangjin and Steve
to provide me advices on release process.

I'll push the release bits and send out an announcement for 2.6.3 soon.
