Thanks Sangjin for the link to the previous discussions on this! I think that helps answer Steve's questions.
As decided on that thread [1], YARN-5355 as a feature branch was merged to trunk via "git merge --no-ff" . Although trunk already had TSv2 code (alpha1) prior to this merge, we chose to develop on a feature branch YARN-5355 so that we could control when changes went into trunk and didn't inadvertently disrupt trunk. Is the latest merge causing any conflicts or issues for s3guard, Steve? thanks Vrushali [1] https://lists.apache.org/thread.html/43cd65c6b6c3c0e8ac2b3c76afd9eff1f78b177fabe9c4a96d9b3d0b@1440189889@%3Ccommon-dev.hadoop.apache.org%3E On Wed, Aug 30, 2017 at 2:37 PM, Sangjin Lee <sj...@apache.org> wrote: > I recall this discussion about a couple of years ago: > https://lists.apache.org/thread.html/43cd65c6b6c3c0e8ac2b3c76afd9ef > f1f78b177fabe9c4a96d9b3d0b@1440189889@%3Ccommon-dev.hadoop.apache.org%3E > > On Wed, Aug 30, 2017 at 2:32 PM, Steve Loughran <ste...@hortonworks.com> > wrote: > >> I'd have assumed it would have gone in as one single patch, rather than a >> full history.
