This is the first public release of Chukwa.You can get it from the Apache distribution mirrors.
See the Chukwa 0.3.0 Release Notes for details. Alternatively, you can look at the Jira issue log for all releases. Note that we've been updating the documentation, in response to early user feedback. You should consult the Apache copy of the documentation, rather than the copy included with the release.
