(Nitpicking) Why set it to a directory named "tmp"? The dfs.name.dir is where the NameNode stores all its meta data related to the data across the DataNodes. I'd give it a good name than tmp, which gives a sense that it isn't important; while it is VERY important for this directory to exist in a usable cluster. -- Harsh J www.harshj.com
