Jim, Most components of hadoop now have a document branch per release, that documentation is inline and is generated by forest. Anything that you find not on the wiki, with a version number, should have a more up to date page.
For example: http://hadoop.apache.org/common/ Drop down 'Documentation' Release 0.18.3 Release 0.19.2 Release 0.20.1 Usually you will find a fresher documentation page: http://hadoop.apache.org/common/docs/r0.20.1/hod_user_guide.html On Mon, Dec 28, 2009 at 12:14 PM, Jim Twensky <jim.twen...@gmail.com> wrote: > Hi, > > I'd like to get Hadoop running on a large University cluster which is > used by many people to run different types of applications.
