With the latest release of Hadoop 2.2 I see that the release notes mentions that this version has significant improvements for running Hadoop on Windows. I downloaded Hadoop 2.2 yesterday and I saw lot of .cmd file alon with .sh files which ensures that this version has scripts and batch files for running Hadoop on Windows environment. However while looking at the Apache Hadoop documentation I couldn't find any step-by-step instructions on how to install and run this newer version on Windows. Besides this it looks like that the newer version has YARN architecture embedded in it and the old configurations provided on some of the tutorials online may be outdated and not applicable anymore. Is there any good documentation for Hadoop 2.2 available online ? I want it specifically for running Hadoop under Windows.
