-File permissions in HDFS
Steve Lewis 2012-12-06, 19:35
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
