Hi again,

   I guess my questions are easy..

Since I'm installing hadoop in my school machine I have to veiw  
namenode online via hdfs://host-name:50070 instead of the default link  
provided by Hadoop Quick Start. (ie.hdfs://localhost:50070).

   Do you think I should set my hadoop.tmp.dir to the machine I'm  
currenlty working  on and I can do the default way?
                      Thank you,

   Maha

Hi

The tmp directory is local to the machine running the hadoop system,  
so if your hadoop is on a remote machine, tmp directory has to be on  
that machine

Your question is not clear to me e.g. what you want to do?

Sorry I'm confused. The story is:

   I ssh into my school-account using my home-computer and installed  
hadoop in school directory. I used to open the browser of  
Hadoop-Quick-Start (hdfs://localhost:50070) from my home computer and  
it showed me the file-system. Yesterday, however, I only wrote the  
property hadoop.tmp.dir = /cs/student/maha into core-site.xml, then  I  
couldn't open hdfs://localhost:50070 on my home computer. I had to  
type hdfs://school-host:50070 to see it.

   I want to use the default link again using my home computer.

   Thanks,
   Maha

Hi Maha ,

I don't think the hadoop.tmp.dir relates the problem of web ui. The
web ui is bind to 0.0.0.0:50070
And localhost is mapped to 127.0.0.1 of your home machine in your client side.

Well I went to check. Now, I'm using the school machine and the UI  
from quick start worked fine ie. hdfs://localhost:50070. looking at my  
fileSystem the temporary directory created has system file in it. is  
that why?

     /cs/student/maha/tmp/mapred/system

   I'm able to use the "localhost" instead of typing
    hdfs://school-host-machine:50070

    I think I need a Networks course.
