driving the project forward and making timely releases - see discussion on hadoop-0.23 with

Arun makes a good point which is that the Apache project depends on 
contributions from the community to thrive. That includes

  -bug reports
  -patches to fix problems
  -more tests
  -documentation improvements: more examples, more on getting started, 
troubleshooting, etc.

If there's something lacking in the codebase, and you think you can fix 
it, please do so. Helping with the documentation is a good start, as it 
can be improved, and you aren't going to break anything.

Once you get into changing the code, you'll end up working with the head 
of whichever branch you are targeting.

The other area everyone can contribute on is testing. Yes, Y! and FB can 
test at scale, yes, other people can test large clusters too -but nobody 
has a network that looks like yours but you. And Hadoop does care about 
network configurations. Testing beta and release candidate releases in 
your infrastructure, helps verify that the final release will work on 
your site, and you don't end up getting all the phone calls about 
something not working
