Subject Re: [VOTE] Release Apache Hadoop 2.7.2 RC2
Date Tue, 19 Jan 2016 23:25:04 GMT
The JIRA YARN-4610 links YARN-3434 <https://issues.apache.org/jira/browse/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.

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.

for your quick perusal.

we decided to keep the parallel 2.6.x and 2.7.x releases incremental, see [4] for this discussion.
