YARN-6622 is now committed to 2.9. We could backport YARN-5258 and
YARN-6622 for 2.8, but it'll take some editing. We'll have to check to
see what features are unsupported in 2.8 and remove those from the
docs. Not a huge effort overall, though. Probably a hour's work. I
may have time to try do it later this week. Anyone else want to volunteer?

I don't think this -1 is reasonable, because:
- If you look at YARN-6622 closely, it targets to fix a problematic
documentation work on YARN-5258 which get checked into 2.9 and 3.0 branch only.
It means it targets to fix a problem that 2.8.2 never exists.
...we're not going to document security implications- which include
escalations to root- because we don't have _any_ documentation? Why
don't we backport the documentation?
- New docker container support (replace of old DockerContainerExectutor) is
still an alpha feature now which doesn't highlight in 2.8 major
features/improvement (http://hadoop.apache.org/docs/r2.8.0/index.html). So
adding documentation here is also not a blocker.
YARN-6622 is *documenting* the fact that this is an alpha feature and
that it shouldn't be enabled in secure environments. How are users
supposed to make this determination without it?
Vote still continue until a real blocker comes.
Soright. I remain -1. -C

-1 (binding)
I don't think we should release this without YARN-6622.
Since this doesn't happen often: a -1 in this case is NOT a veto.
Releases are approved by majority vote of the PMC. -C

Thanks Mikols for notifying on this. I think docker support is general known as
alpha feature so document it as experimental is nice to have but not a blocker
for 2.8.2. I also noticed that our 2.7.x document
(https://hadoop.apache.org/docs/r2.7.4/hadoop-yarn/hadoop-yarn-site/DockerContainerExecutor.html)
without mentioning docker support is experimental. We may need to fix that as
well in following releases.
I can also add it (mentioning docker container support feature is experimental)
to release message in public website just like previous release we call
2.7.0/2.8.0 as non-production release.
I think vote should continue until we could find a real blocker.
Thanks,
Junping

Hello Junping,
Thank you for working on this. Should not YARN-6622 be addressed first? "Summary:
Document Docker work as experimental".
Thank you,
Miklos

Thanks Junping for doing this!
+1 (non-binding)
- Download the hadoop-2.8.2-src.tar.gz file and checked the md5 value
- Build package using maven (skipping tests) with Java 8
- Spin up a test cluster in Docker containers having 1 master node (NN/RM) and
3 slave nodes (DN/NM)
- Operate the basic HDFS/YARN operations from command line, both client and
admin
- Check NN/RM Web UI
- Run distcp to copy files from/to local and HDFS
- Run hadoop mapreduce examples: grep and wordcount
- Check the HDFS service logs
All looked good to me.
