Trouble Submitting Job as another User

Hi,

I am trying to set up a Hadoop cluster so that any of our users can
access HDFS and submit jobs and I am having trouble with this.
I added a HDFS path for mapred.system.dir in mapred-site.xml as
suggested in an FAQ.

I start/stop the cluster with system user _hadoop.
I would like to be able to access HDFS and submit jobs as user "ryan"
(and other users on the system). When I attempt to copy a directory
from local FS to HDFS I get,

10/04/03 14:35:27 INFO ipc.Client: Retrying connect to server:
localhost/127.0.0.1:9000. Already tried 0 time(s).
.
.
.

How can I accomplish what I am trying to do?

Thanks in advance,
Ryan

Sorry, 

I don't know why my post didn't make it...

Here's what I was saying...

If you go in to hadoop, create a home directory for the user and then change ownership and permissions, the user should then be able to use the cloud.

An example: User : John Doe , Unix ID: jdoe

So you'd create an HDFS directory : /user/jdoe
Change the ownership jdoe:jdoe for /user/jdoe
and that should be it.

No?

Yes. I just tried that then stopped mapred and dfs and restarted them.
No change.

I am still only able to connect to HDFS only as _hadoop.

Did you disable the permissions for HDFS?

 <property>
    <name>dfs.permissions</name>
    <value>false</value>
  </property>
