How To Contribute
- Checkout Code from: http://git-wip-us.apache.org/repos/asf/ambari.git
- Open an Apache Jira corresponding to the internal Jiraissue at hand
Please make sure you use the external Apache jira for most of the design updates (adding detailed descriptions, comments, etc)
Create a patch and upload to the external Apache jira
As soon as you think the patch is ready for review please mark the patch as Patch Available by clicking on the “Submit Patch” button
Request 2 of the Ambari Team Committers to review the patch via the code review process below
Please note that if the patch is not involved - one committer should suffice
On review completion and any further updates, the reviewer adds a comment to the external jira approving the patch (“+1”)says +1 for the patch
Note that there needs to be 2 +1's if you have 2 reviewers for involved codebase
NOTE: On backend non UI changes reviewers please make sure tests are attached to each jira. If there is special case, please make sure there is a good explanation for not having a test case.
After the reviewer has approved the patch, the person who is assigned the jira is responsible for getting it committed to external jira - so in case you do not have commit rights please find one of your team members to do it for you.
Please make sure the committer who has reviewed commits the patch to the respective branch in Ambari
Use https://cwiki.apache.org/confluence/display/AMBARI/How+to+Commit on how to commit to svn
