bq. I don't think it's a lot to ask that feature leads shoot an email to
the release manager of their target version. DISCUSS emails right before a
proposed merge VOTE are way too late, it ends up being a fire drill where
we need to scramble on many fronts.
Yes, I have been thinking about this too

Jonathan, thanks for the heads up. I don't have much familiarity with YARN,
but gave the PBs and pom changes a look, and left a few small comments on
the umbrella JIRA.
This seems like a smaller change than some of the other branch merges we're
discussing, but I'm again reticent about adding scope
Here's a summary of some 1-on-1 conversations I had with contributors of
the different features I'm tracking.

* Target version: 3.1.0, maybe 3.0.0 GA
* We're resolving some design discussions on JIRA. Plan is to do some MVP
work on the API to get this into

Hi Andrew,
Thanks for starting the discussion - we have a feature YARN-5734 for API
based scheduler configuration that I feel is pretty close to merge (also "a
few weeks"). It's almost completely code and API additions and we were
careful to design it so that it's compatible (feature is also turne
Resource profile is similar to TSv2, the feature is:
- Alpha feature, we will not freeze new added APIs. And all added APIs are
explicitly marked to @Unstable.
- Allow rolling upgrade from branch-2.
- Touched existing code, but we have, and will continue tests to make sure
changes are safe.

Hi Jason,
I agree with this proposal. I'll start another email thread spelling this
out, and gather additional feedback.
Best,

Hi Rohith,
Given that we're advertising TSv2 as an alpha feature, I think we're
allowed to break compatibility. Let's make sure this is clear in the
release notes and documentation.
That said, with TSv2 phase 2, is the API going to be frozen? The umbrella
JIRA refers to "TSv2 alpha2" which indica

I can see a need for branch-3.0, but please do not create branch-3. Doing
so will relegate trunk back to the "patch pu
Hi Andrew
Thanks for update on release plan!
I would like to discuss specifically regarding compatibility of releases.
What is the compatibility to be maintained for GA if we don't merge to
beta1 release? IIUC, till now all the releases were alpha where
compatibility was not that important. All t
Glad to see the discussion continued in my absence :)

Also, when people +1 a merge, can they please describe if they did testing
/ use the feature in addition to what is already described in the thread?

For timeline service v2, we have completed all subtasks under YARN-5355

We initiated a merge-to-trunk vote [2] yesterday.

Agreed. I was very clearly not advocating for rushing in features. If you have
followed my past emails, I have only strongly advocated features be worked in
branches and get merged when they are in a reasonable state.
Each branch contributor group should look at their readiness and merge stuff i
We should avoid turning this into a replay of Apache Hadoop 2.6.0 (and
to a lesser degree, 2.7.0 and 2.8.0) where a bunch of last minute
“experimental” features derail stability for a significantly long period of
time.

Andrew,
Each of the branches below have been created more than a year ago (!) and have
been consistently worked upon and are now finally seeing the light of the day.
When they are "few weeks” away, pushing them out by 7 *more* months just
doesn’t make sense.
While I deeply appreciate the push
Hi folks,
As you might have seen, we've had a number of branch merges floated this
past week targeted for 3.0.0-beta1, which is planned for about a month from
now.
In total, I'm currently tracking these branches:
YARN-2915: YARN federation (recently merged)
HADOOP-13345: S3Guard (currently being
