[DISCUSS] 2.6.x line releases
It's been a while since we had a release on the 2.6.x line. Is it time to
get ready for a 2.6.5 release? Are folks using and relying on releases on
2.6.x? If there is enough interest, I could take that on. Let me know.
I also want to gauge the community's interest in maintaining the 2.6.x
line. How long do we maintain this line? What would be a sensible EOL
policy? Note that as the main code lines start diverging (java version,
features, etc.), the cost of maintaining multiple release lines does go up.
I'd love to hear your thoughts.
Regards,
Sangjin

Thanks Chris for stepping up! I'll work with Chris to get started on the
2.6.5 release soon.

Thanks for pointing it out Allen. I'll work on an addendum 2.6 patch for
HADOOP-12800.

It wasn’t a vote. PMC doesn’t vote on code-changes.
It was an extensive community discussion. We arrived at that decision to reflect the reality that not many users were running JDK6 anyways at that point of time.
Sorry to bust the bubble, this is not one of those things that supports your propaganda about how branch-2 is bust.

2.6 builds on JDK6 and JDK7. 2.x, where x>6, builds on JDK7 and JDK8. [1] This should have been a big red flag in that patch:
---
+RUN apt-get install -y oracle-java8-installer
---
(It's interesting that ~2 years later, we're still dealing with the fallout of the JRE compatibility break in 2.7. I wonder how many of those PMCs who voted for it are still actively involved.)
[1] For completeness, 3.x only builds on JDK8 but probably not JDK9, given log4j 1.x, etc, etc.

Someone probably just needs to invest some time in modifying the Dockerfile in 2.6 to actually meet the build requirements. Right now, it's way way wrong.

We are using 2.6 releases and would like to see 2.6.5.
One related issue, pre-commit is not working for 2.6 (see comment from
Allen
https://issues.apache.org/jira/browse/HDFS-10653?focusedCommentId=15388621&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15388621).
Should we fix for the purpose of the release?

Hi Sangjin,
I'm thinking it's time for 2.6.5 release. Now there are 51 fixed issues
in 2.6.5 and the number is more than 2.6.4 (47).
> How long do we maintain this line? What would be a sensible EOL policy?
Ideally 5 years, because most of our customers in Japan are using Hadoop
cluster without upgrading for about 5 years. However, it's probably
impossible for us to achieve the long term maintenance in the community
because the maintenance cost is too high. Therefore, my answer is
"longer is better".
By the way, I'm thinking we can reduce the maintenance cost by selecting
which branch to maintenance for a long time. An example is Ubuntu LTS.
Ubuntu Server LTS is maintained for 5 years but the other releases are not.
Regards,
Akira
