The source is your friend. And perhaps a good Java IDE too. I use Eclipse + F3. But since you ask, you may begin at the wiki: http://wiki.apache.org/hadoop/FrontPage There's stuff there not many see, and those pretty much cover enough to get you started at the right places :)
About a document, I guess O'Malley's Hadoop MR Arch one would help, but nothing beats reading sources the way its supposed to be done: http://docs.huihoo.com/apache/hadoop/HadoopMapReduceArch.pdf On Fri, Oct 22, 2010 at 8:01 PM, Ahmad Shahzad <ashahz...@gmail.com> wrote: > Hi ALL, > Is there any documentation or guide or any presentation about > what happens inside hadoop.
