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.
