Re: [VOTE] Merge feature branch YARN-5355 (Timeline Service v2) to trunk

Yes, I had used "git merge --no-ff" while merging ATSv2 to trunk. Maintaining history I believe can be useful as it can make reverts easier if at all required. And can be an easy reference point to look at who had contributed what without having to go back to the branch. Regards, Varun Saxena. O

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 d

The "git" way of doing things would be to rebase the feature branch on master (trunk) and then commit the patch stack. Squashing the entire feature into a 10 MB megapatch is the "svn" way of doing things. The svn workflow evolved because merging feature branches back to trunk was really painful i

I'd have assumed it would have gone in as one single patch, rather than a full history. I don't see why the trunk needs all the evolutionary history of a build. What should our policy/process be here? I do currently plan to merge the s3guard in as one single squashed patch; just getting HADOOP
