Subject Re: Where is the 'user' directory
Date Thu, 22 Apr 2010 17:45:49 GMT
HDFS is a user space file system meaning it is a virtual file system,
different from the OS file systems (like ext3, xfs). To access files
on HDFS you use the 'hadoop fs' command. Ex:

hadoop fs -ls /

This is different than your OS / partition and will contain the same
view as the web UI.
