Now that checkstyle conformance is more prominently part of the build process, I feel a need to bring this part process into the IDEs in the name of efficiency. I have posted a patch that teaches eclipse checkstyle-cs plugin to use the checkstyle rules present in the hadoop code base. This integration is a huge time savings for people using eclipse trying to eliminate all the checkstyle warnings in their patch.
Any eclipse users that are very familiar with the build process are welcome to review and give feedback. jeagles
