Where is the 'user' directory

[Rana Aich <ra...@yahoo.com>]

Hi,

I'm a newbie in this sphere...I've downloaded Hadoop yesterday and am going thru the commands listed in the Quick Start page.

I went to http://localhost:50070 the DFS home page.
>From there I clicked 'Browse the File System' link.

There I could see two directories:
/tmp
/user

and all there subdirectories and files.

But when I go to my File sytem I'm unable to find 'user' directory. Though the DFS home page lists it under "/" (root directory) - I couldn't find any directory of that name. Interestingly /tmp is there.

I ran 'find / -name' as Superuser for "user" directory but there is none.

Am I missing something here?

Thanking you all in advance.

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.
