Subject File permissions in HDFS
Date Thu, 06 Dec 2012 19:35:00 GMT
  I am running Hadoop jobs on a cluster whose jobtracker and
file system are on a machine in my network called mycluster.


 If I set in the configuration as shown , set the configuration in a Tool
and call run
the Tool run command, the job runs on the cluster.

My problem is that even when in the configuration I say

the job runs as the local user.

On my cluster the files and directories are created as the local user
In my cluster hdfs-site.xml has the property


and in hadoop-policy.xml
all properies are set to * as shown below

On my cluster things work but on other clusters they do not. The
documentation is not very
clear on permissions and I would like a good discussion on this issue.
Ideally I would want
to set the user (and provide a password) for a hadoop job but still run on
the local box
