That's reasonable, especially if we don't take nearly as long for 2.7.3. Note
that there are almost 50 JIRAs already committed to 2.7.3, so hopefully we'll
have a plan for that soon.
+1 (binding) for 2.7.2 RC2.

The JIRA YARN-4610 links YARN-3434 as the one causing the breakage, and
YARN-3434 already exists in 2.7.1 itself. That categorizes the new issue as an
existing bug.
If you agree with that sentiment, and given that there is a clear work-around,
in the interest of progress of 2.7.2 (we have spent > 2 months on this now),
I’d like to move forward.
Please LMK what you think.
Thanks+Vinod

We have been running a release derived from 2.7 on some of our clusters, and we
recently hit a bug where an application making large container requests can
drastically slow down container allocations for other users in the same queue.
See YARN-4610 for details. Since
yarn.scheduler.capacity.reservations-continue-look-all-nodes is on by default,
I think we should fix this. If we decide to ship 2.7.2 without that fix then
the release notes should call out that JIRA and mention the workaround of
setting yarn.scheduler.capacity.reservations-continue-look-all-nodes to false.

Subject: [VOTE] Release Apache Hadoop 2.7.2 RC2
Hi all,
I've created an updated release candidate RC2 for Apache Hadoop 2.7.2.
As discussed before, this is the next maintenance release to follow up 2.7.1.
The RC is available for validation at:
http://people.apache.org/~vinodkv/hadoop-2.7.2-RC2/
The RC tag in git is: release-2.7.2-RC2
The maven artifacts are available via repository.apache.org
<http://repository.apache.org/> at
https://repository.apache.org/content/repositories/orgapachehadoop-1027
<https://repository.apache.org/content/repositories/orgapachehadoop-1027>
The release-notes are inside the tar-balls at location
hadoop-common-project/hadoop-common/src/main/docs/releasenotes.html. I hosted
this at http://people.apache.org/~vinodkv/hadoop-2.7.2-RC2/releasenotes.html
<http://people.apache.org/~vinodkv/hadoop-2.7.2-RC1/releasenotes.html> for your
quick perusal.
As you may have noted,
- I terminated the RC1 related voting thread after finding out that we didn’t
have a bunch of patches that are already in the released 2.6.3 version. After a
brief discussion, we decided to keep the parallel 2.6.x and 2.7.x releases
incremental, see [4] for this discussion.
- The RC0 related voting thread got halted due to some critical issues. It
took a while again for getting all those blockers out of the way. See the
previous voting thread [3] for details.
- Before RC0, an unusually long 2.6.3 release caused 2.7.2 to slip by quite a
bit. This release's related discussion threads are linked below: [1] and [2].
Please try the release and vote; the vote will run for the usual 5 days.
Thanks,
Vinod
