Patches for trunk should be named according to the Jira: jira-xyz. Patches for a non-trunk branch should be named jira-xyz-branch. This naming convention allows the pre-commit tests to automatically run against the correct branch new capability coming soon; see HADOOP It's OK to upload a new patch to Jira with the same name as an existing patch, Jira will just make the previous patches grey. They're still listed, sorted by date.
Before submitting your patch, you are encouraged to run the same tools that the automated Jenkins patch test system will run on your patch. This enables you to fix problems with your patch before you submit it. Run this command from a clean workspace ie svn stat shows no modifications or additions as follows:. Some things to note:. Run the same command with no arguments to see the usage options. To apply a patch either you generated or found from JIRA, you can issue.
If you are an Eclipse user, you can apply a patch by : 1. Right click project name in Package Explorer , 2. Or perhaps you have changed something in common, and need to verify that these changes do not break the existing unit tests for HDFS and MapReduce. Hadoop's build system integrates with a local maven repository to support cross-project development. Use this general workflow for your development:. Publish your new common jar to your local mvn repository:. A word of caution: mvn install pushes the artifacts into your local Maven repository which is shared by all your projects.
Finally, patches should be attached to an issue report in Jira via the Attach File link on the issue's Jira. Please add a comment that asks for a code review following our code review checklist. When you believe that your patch is ready to be committed, select the Submit Patch link on the issue's Jira. Submitted patches will be automatically tested against "trunk" by Hudson , the project's continuous integration engine. If your issue contains multiple patch versions, Hudson tests the last patch uploaded.
Folks should run mvn clean install javadoc:javadoc checkstyle:checkstyle before selecting Submit Patch. Tests must all pass. Javadoc should report no warnings or errors. Checkstyle's error count should not exceed that listed at Checkstyle Errors Hudson's tests are meant to double-check things, and not be used as a primary patch tester, which would create too much noise on the mailing list and in Jira.
Submitting patches that fail Hudson testing is frowned on, unless the failure is not actually due to the patch. If your patch involves performance optimizations, they should be validated by benchmarks that demonstrate an improvement.
If your patch creates an incompatibility with the latest major release, then you must set the Incompatible change flag on the issue's Jira 'and' fill in the Release Note field with an explanation of the impact of the incompatibility and the necessary steps users must take.
If your patch implements a major feature or improvement, then you must fill in the Release Note field on the issue's Jira with an explanation of the feature that will be comprehensible by the end user.
Please be patient. Committers are busy people too. If no one responds to your patch after a few days, please make friendly reminders. Please incorporate other's suggestions into your patch if you think they're reasonable. Finally, remember that even a patch that is not committed is useful to the community.
Should your patch receive a "-1" from the Hudson testing, select the Cancel Patch on the issue's Jira, upload a new patch with necessary fixes, and then select the Submit Patch link again. Committers: for non-trivial changes, it is best to get another committer to review your patches before commit. Please also try to frequently review things in the patch queues:. Hadoop Common Review Queue.
Hadoop MapReduce Review Queue. Please comment on issues in Jira, making their concerns known. Please also vote for issues that are a high priority for you. Please refrain from editing descriptions and comments if possible, as edits spam the mailing list and clutter Jira's "All" display, which is otherwise very useful. Instead, preview descriptions and comments using the preview button on the right before posting them.
Keep descriptions brief and save more elaborate proposals for comments, since descriptions are included in Jira's automatically sent messages.
If you change your mind, note this in a new comment, rather than editing an older comment. The issue should preserve this history of the discussion. Contributors should join the Hadoop mailing lists. In particular, the commit list to see changes as they are made , the dev list to join discussions of changes and the user list to help others. Apache contributor documentation.
