Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "HowToCommitWithGit" page has been changed by karthikkambatla: https://wiki.apache.org/hadoop/HowToCommitWithGit?action=diff&rev1=23&rev2=24 Hadoop uses git for version control. The writable repo is at - TODO ==== Initial setup ==== - We try to keep our history all linear and avoid merge commits. To this end, we highly recommend using git pull --rebase.

'''CHANGES.txt:''' Add an entry in CHANGES.txt, at the end of the appropriate section. This should include the JIRA issue ID, and the name of the contributor. + 1. '''Commit locally:''' Commit the change locally to the appropriate branch (should be ''master'' if it is not a feature branch) using {{{git commit -a -m <commit-message>}}}. The commit message should include the JIRA issue id, along with a short description of the change and the name of the contributor if it is not you. ''Note:'' Be sure to get the issue id right, as this causes JIRA to link to the change in git (use the issue's "All" tab to see these). Verify all the changes are included in the commit using {{{git status}}}. If there are any remaining changes (previously missed files), please commit them and squash these commits into one using {{{git rebase -i}}}. + 1. '''Pull latest changes from remote repo:''' Pull in the latest changes from the remote branch using {{{git pull --rebase}}} (--rebase is not required if you have setup git pull to always --rebase). Verify this didn't cause any merge commits using {{{git log [--pretty=oneline]}}} + 1. '''Push changes to remote repo:''' Build and run a test to ensure it is all still kosher. Push the changes to the remote (main) repo using {{{git push <remote> <branch>}}}. + 1. If the changes were to master, cherry-pick the changes to other appropriate branches via {{{git cherry-pick -x <commit>}}}. The -x option records the source commit. Make sure to resolve any conflicts. + 1. Resolve the issue as fixed, thanking the contributor. Always set the "Fix Version" at this point, but please only set a single fix version, the earliest release in which the change will appear. '''Special case'''- when committing to a ''non-mainline'' branch (such as branch-0.22 or branch-0.23 ATM), please set fix-version to either 2.x.x or 3.x.x appropriately too. + This How-to-commit [[http://www.youtube.com/watch?v=txW3m7qWdzw&feature=youtu.be|video]] has guidance on the commit process, albeit using svn. Most of the process is still the same, except that we now use git instead. - 1. Add an entry in CHANGES.txt, at the end of the appropriate section.
