> Superuser privileges required to do "df"

> Project: Hadoop Core
> Issue Type: Wish
> Components: dfs, libhdfs
> Affects Versions: 0.18.1
> Reporter: Brian Bockelman
> Assignee: Craig Macdonald
> Priority: Minor
> Attachments: fuse_statfs.patch, fuse_statfs_trunk.patch,

> Original Estimate: 0.17h
> Remaining Estimate: 0.17h
>
> super user privileges are required in DFS in order to get the file system
> statistics (FSNamesystem.java, getStats method). This means that when HDFS
> is mounted via fuse-dfs as a non-root user, "df" is going to return
> 16exabytes total and 0 free instead of the correct amount.
> As far as I can tell, there's no need to require super user privileges to see
> the file system size (and historically in Unix, this is not required).
> To fix this, simply comment out the privilege check in the getStats method.
