Apache is a meritocracy. That is, once someone has shown sufficient sustained committment to a project (and the ASF) they can be voted in as a committer.
First of all you need to get involved and contribute via the user and developer mail lists, Wiki and forums (if any), provide patches for documention, work on the issue tracker or submit code patches.
If your work shows merit, the PMC for the project may hold a vote to invite you to become a committer.
Note that becoming a committer is not just about submitting some patches; it's also about helping out on the development and user discussion lists, helping with documentation and the issue tracker, and showing long-term interest.
