Re:

2017-07-24 Thread Junping Du 
I have done the change.

All committers,

  2.8.2 release is supposed to be a stable/production release for 
branch-2.8. For commits to go for 2.8.2 release (only important and low risk 
bug fixes), please commit to trunk, branch-2, branch-2.8 and branch-2.8.2. For 
unimportant or high risk bug fixes/improvements, please commit to branch-2.8 
(trunk/branch-2) only and mark JIRA fixed as 2.8.3. Thanks for your cooperation!


Thanks,


Junping

Nice catch, Brahma. Actually, this is not supposed to be happen as we all 
should know the patch should firstly get landed on branch-2.8 (as well as 
trunk, branch-2) before landed on branch-2.8.2. Anyway, we will always check 
JIRAs claim to fixed in a specific release version with commits actually 
landing on the releasing branch before kicking off RC. So, I am not too worry 
about this mistaking behaviors as it happens in every releases.

If no other concerns, I will do the branch update in next 30 minutes.

Already get back from Daniel who is from ASF INFRA team, I plan to do following 
operations on next Monday morning:
1. Drop current branch-2.8.2 and recut branch-2.8.2 from branch-2.8
2. Drop abandoned branch-2.8.1 and rename branch-2.8.1-private to branch-2.8.1 
where we just released 2.8.1 from.
I will also adjust fix version on all affected JIRA accordingly.

If you have any concerns on above operations, please raise it before the end of 
this Sunday (7/23).

Junping,

If we are looking at a month, I’d not rebranch branch-2.8.2 right now given how 
these things go. We can just continue to commit on branch-2.8 for now.

I also think we should just follow up with ASF INFRA and clean up the branches
 - Delete branch-2.8.2 so that we can recreate it afresh a little later.
 - branch-2.8.1 is also stale and it should be deleted. branch-2.8.1-private 
should be renamed to branch-2.8.1

Thanks

[DISCUSS] Looking to a 2.9.0 release

2017-07-24 Thread Subru Krishnan 
Folks,

With the release for 2.8, we would like to look ahead to 2.9 release as
there are many features/improvements in branch-2 (about 1062 commits), that
are in need of a release vechile.

Here's our first cut of the proposal from the YARN side:

   1. Scheduler improvements (decoupling allocation from node heartbeat,
   allocation ID, concurrency fixes, LightResource etc).
   2. Timeline Service v2
   3. Opportunistic containers
   4. Federation

We would like to hear a formal list from HDFS & Hadoop (& MapReduce if any)
and will update the Roadmap wiki accordingly.

Considering our familiarity with the above mentioned YARN features, we
would like to volunteer as the co-RMs for 2.9.0.

We want to keep the timeline at 8-12 weeks to keep the release pragmatic.

Feedback?
