data under Hadoop is stored as blocks and is not visible using normal Unix commands such as "ls" etc. to see your files, use
hadoop dfs -ls your files will actually be stored as follows: > Specify directories for dfs.name.dir and dfs.data.dir in conf/hadoop-site.xml. These are used to hold distributed filesystem data on the master node and slave nodes respectively. Note that dfs.data.dir may contain a space- or comma-separated list of directory names, so that data may be stored on multiple devices. > Miles 2008/10/11 Amit k.
