hadoop files not viewed

Hi,

I am new for hadoop. I have installed "Multi-Node Cluster" successfully and its working fine.

I have copied my "php" files using hadoop command in the following path "/user/hadoop/input" path. Now i need to open that "index.php" file which located in the above path using apache, so i configure that path in apache. I have tried in Ubuntu, and edit the below two lines in the /etc/apache2/sites-enabled/000-default file.

DocumentRoot /user/hadoop/input
<Directory /user/hadoop/input>

 But my "index.php" not viewed, Just throw an following error.

The requested URL /input/index.php was not found on this server.

Please check and advise me is there any way to configure that "php" path..
Thanks for looking into this.
