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.
> Support permissions in fuse-dfs
> -------------------------------
>
> Key: HADOOP-3536
> URL: https://issues.apache.org/jira/browse/HADOOP-3536
> Project: Hadoop Core
> Issue Type: New Feature
> Components: contrib/fuse-dfs
> Reporter: Craig Macdonald
> Attachments: getlogininfo.c
>
>
> 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
