> Let's say root path ("/") is the encryption zone, and there is a file called "/test"
in root path.
> {code}
> dfs.getTrashRoot(new Path("/"))
> {code}
> returns "/user/$USER/.Trash",
> while
> {code}
> dfs.getTrashRoot(new Path("/test"))
> {code} 
> returns "/.Trash/$USER".
> The second behavior is not correct. Since root path is the encryption zone,  which means
all files/directories in DFS are encrypted, it's more reasonable   to return  "/user/$USER/.Trash"
no matter what the path is. 
> Please see the attachment to know how to reproduce this issue.
