This refers to formatting Hadoop's DFS filesystem, not formatting a
linux volume. Hadoop's DFS filesystem in implemented on top the local
filesystems of your cluster. Hadoop does not require reformatting of
linux filesystem volumes. Formatting a Hadoop DFS filesystem simply
creates a few files and directories in a configured location on your
local filesystem (removing any files that already existed there).
Does that make more sense?

hello all,

The first step to starting up your Hadoop installation is formatting
the file system. You need to do this the first time you set up a
Hadoop installation. Do not format a running file system, this will
cause all your data to be erased. To format the file system, run the
command:
i am confused by the instruction there...is that mean
1. I need to make an empty partition for hadoop first, without
formatting it?
2. Is that mean haoop will only run on Linux as the file system can't
be supported by windows?
3. are there any complete step by step tutorial for newbie?
thanks.
