Arun, One of the main reasons I built the source is to start contributing. :)
Although, it's clear how to make code contributions in http://wiki.apache.org/hadoop/HowToContribute. I'm a bit unclear on how to make documentation contributions. Do I just create a JIRA and attach a text file, so that it can be included in the wiki? Also, the quick start page has a small error as well at http://hadoop.apache.org/common/docs/r0.20.0/quickstart.html. A grep doesn't seem to show where it's generated from. Can you help me out here as well?
