Re: Hadoop 3.1.0 release discussion
What's the status on resource profiles? I believe there are still a couple of open JIRAs to rethink some of the design choices.

As we discussed in the previous email thread [1], I'd like to restart 3.1.0 release plans. a) Quick summary: a.1 Release status We started 3.1 release discussion on Sep 6, 2017 [1]. As of today, there’re 232 patches loaded on 3.1.0 alone [2], besides 6 open blockers and 22 open critical issues. a.2 Release date update Considering delays of 3.0-GA release by month-and-a-half, I propose to move the dates as follows - feature freeze date from Dec 15, 2017, to Jan 30, 2018 - last date for any branches to get merged too; - code freeze (blockers & critical only) date to Feb 08, 2018; - release voting start by Feb 18, 2018, leaving time for at least two RCx - release date from Jan 15, 2018, to Feb 28, 2018; Unlike before, I added an additional milestone for release-vote-start so that we can account for voting time-period also. This overall is still 5 1/2 months of release-timeline unlike the faster cadence we hoped for, but this, in my opinion, is the best-updated timeline given the delays of the final release of 3.0-GA. b) Individual feature status: I spoke to several feature owners and checked the status of un-finished features, following are status of features planned to 3.1.0: b.1 Merged & Completed features: * (Sunil) YARN-5881: Support absolute value in CapacityScheduler. * (Wangda) YARN-6223: GPU support on YARN.
