Subject [jira] Updated: (HADOOP-3536) Support permissions in fuse-dfs
Date Mon, 23 Jun 2008 18:22:45 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3536?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Craig Macdonald updated HADOOP-3536:
------------------------------------

    Attachment: getlogininfo.c

Code to determine:
 * uid -> username
 * uid -> username,all groupnames

This code could be used to set the hadoop.job.ugi property to obtain the correct FileSystem
object for each user accessing the DFS.

> Currently permissions are unsupported by fuse-dfs.
> This manifests itself as two issues:
>  * Users accessing a fuse-dfs mount do so as the user running fuse_dfs executable. In
this case, it would be better to run fuse-dfr as some privileged user, and use Hadoop API
calls determine whether the current user was privileged enough to perform the action.
>  * Users cannot view/change permissions on the mounted volume. See  HADOOP-3264
