> User A has access to lineitem folder and its subfolders
> User B had access to lineitem folder but not its sub-folders.
> Now when User A runs the "refresh table metadata lineitem" command, the cache 
> file gets created under lineitem folder. This file contains information from 
> the underlying sub-directories as well.
> Now User B can download this file and get access to information which he 
> should not be seeing in the first place.
> This can be very easily reproducible if impersonation is enabled on the 
> cluster.
> Let me know if you need more information to reproduce this issue
