Pete Wyckoff commented on HADOOP-4106:
--------------------------------------
bq. Does the fuse-dfs currently let me read/write files that I dont have
permission to do so?
Yes, it does unconditionally. So, this patch will improve things. the only
thing is you will get an IO error rather than a correct error message saying
you don't have permissions. So, in that respect, this patch is an improvement.
Albeit, getting an IO error rather than a permission error is a little weird. I
guess the question is whether it's preferable to let people see files
unconditionally or get an IO error when they do??
I think getting 4108 committed by Friday isn't possible.
An alternative would be to assume -EPERM when libhdfs gives an error, but that
would be pretty hacky.

> add:
> dfs_chown
> dfs_utime
> dfs_chmod
> Change open to have its own FS on writes (should we do this on reads too??)
> and use it for writes and disconnect when closing the file
> Chane mkdir to open the FS itself and then close it
> also added comments for dfs_access (which needs FileSystem support/libhdfs
> support) and I added the dfs_symlink and truncate since these 3 are the only
> 3 things left as far as functionality.
