Hi Howard, The formatting of the filesystem is with respect to Hadoop File System. It does not involve formatting your local file system. All you need to do is
bin/hadoop namenode -format. This command just creates some files for the namenode in the directory specified as dfs.name.dir. Also, Hadoop does work on Windows. You will need to install cygwin.
