Pete Wyckoff commented on HADOOP-4111:
--------------------------------------
proposal for the short term:
Implement this entirely in fuse-dfs using the hdfsStat structure which has the owner, group and permissions of a file. Use the 'root' user on the box fuse-dfs is running on as the super user.
This can be done relatively quickly and gives basically the right semantics assuming HDFS is "exported" with no_root_squash which since it doesn't implement authenticating users, it really is.
The only downside is fuse-dfs will not then respect the user that is the superuser for HDFS; they would have to sudo command like everyone else.
This does *not* introduce any security holes since the user could directly use the Java client or libhdfs to do any operation fuse-dfs can.
