Pete,
There's a few issues here:
What does fuse support:
* FUSE allows access to the user performing each operation.
* FUSE allows attributes and permissions to be retrieved and set.
What does fuse-dfs not support, but should:
* fuse-dfs should access the DFS as the requesting user "asuser" (thereby
upholding the hadoop security model)
* fuse-dfs should allow permissions to be set & retrieved from the DFS
fuse-dfs is bound by the API provided by libhdfs. In this case, the missing
features are:
* libhdfs should allow connection to the DFS as a given user
* libhdfs should allow permissions to be set and retrieved. HADOOP-3264
I propose splitting this JIRA up into several issues:
* fuse-dfs user impersonation
* fuse-dfs permissions set & get
And add the missing libhdfs dependent JIRA
* Allow connecting username to be specified in libhdfs
This JIRA will remain as an overview issue.

> 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
