| <p>Committers are responsible for reviewing and integrating code changes. |
| The PMC votes to make a contributor a committer based on an assessment |
| of their contributions to the project. Contributions can be made in many |
| ways, and there is no one route to committership. That said, here are |
| the general criteria that the PMC looks for from all potential |
| committers:</p> |
| <ul> |
| <li> |
| <p><strong>A history of sustained contribution to the project.</strong> This is a |
| way for a contributor to demonstrate their expertise in an area, and |
| thus their ability to help review and commit contributions by others |
| in that same area. Sustained contribution is also a way of |
| demonstrating commitment to the project, essentially that someone |
| will continue contributing even after they become a committer.</p> |
| </li> |
| <li> |
| <p><strong>High-quality contributions.</strong> As experienced contributors, |
| committers set an example for others in the project, and help |
| inculcate a culture of high-quality contributions. For code |
| contributions, this means clean, documented code which includes unit |
| tests if appropriate and passes precommit checks. For reviews, this |
| means thorough, actionable feedback, and a +1 vote (even |
| non-binding) only when there is a high degree of confidence in the |
| change.</p> |
| </li> |
| <li> |
| <p><strong>Community involvement.</strong> Contributors are always expected to be |
| polite, constructive, and respectful of others during community |
| interactions. Disagreement can (and will) happen over technical |
| issues, but the discussion should remain friendly and focused on |
| technical merits. Committers also have the additional responsibility |
| of mentoring newer contributors, as well as helping to grow the |
| community through actions like responding to emails on the user and |
| dev list.</p> |
| </li> |
| </ul> |
| <h1 id="example-paths-to-committership">Example Paths to Committership</h1> |
| <p>Here are a few hypothetical example paths to a commit bit:</p> |
| <p><em>Han Meimei</em> works at a big company operating a large Apache Hadoop |
| cluster. While deploying the newest version of Hadoop to her staging |
| cluster, she discovers a number of bugs and performance regressions. She |
| files JIRAs for these issues, and is able to post patches for some of |
| them. On the remaining JIRAs, she works with other community members by |
| doing additional debugging on her cluster and testing and reviewing |
| intermediate patches. Additionally, Han Meimei works with the release |
| manager of the release line, <em>Lei Li</em>, to make sure critical issues are |
| backported to the next maintenance release. Han Meimei also makes an |
| effort to help fix and review other critical issues targeted at the next |
| maintenance release, even though her cluster is not currently affected. |
| She continues doing similar stabilization work for subsequent |
| maintenance releases in this release line, demonstrating her commitment |
| to shipping high-quality upstream releases.</p> |
| <p><em>Elise</em> works at a commercial big data vendor as a developer. Elise |
| ramps up by doing some newbie JIRAs, but then gets involved with a large |
| cross-company development effort happening on a feature branch. Elise |
| helps to review the design of the feature, providing constructive |
| feedback, and works with other community members to divide the work into |
| subtasks. At this point, the PMC grants Elise branch committership to |
| accelerate development. Elise submits good patches for a number of |
| subtasks, and shows care and thoroughness when reviewing and committing |
| code of others. After the feature branch is later merged to trunk, Elise |
| continues to find and fix bugs related to the feature, as well as |
| reviewing code contributions from others.</p> |
| <p><em>Raj</em> works as a test engineer at a commercial big data vendor. Raj |
| notices the lack of integration testing upstream, and contributes a test |
| harness for fault-injection testing which is committed to the project. |
| Raj coordinates with the PMC to get the test harness running on Apache |
| infrastructure, and starts triaging the output and filing JIRAs for |
| relevant bugs with reproductions. Raj helps with gathering logs and |
| reproducing issues, and continues making improvements to the test |
| harness.</p> |
| <p><em>Peter</em> is a technical writer interested in improving Hadoop’s |
| documentation. He starts by fixing outdated information and incorrect |
| examples, reaching out to subject matter experts and exploring the |
| codebase to clarify technical details. As Peter becomes more familiar |
| with the set of documentation, he realizes that a newly contributed |
| feature didn’t include sufficient documentation, and contributes a guide |
| on how to setup and use the feature that also explains some of the |
| design decisions that influenced API design. Peter continues to broaden |
| his doc contributions to more and more areas, and also is active |
| answering user questions on the mailing list. This demonstrates his |
| knowledge of the project, attention to detail, and also his user-focus.</p> |
