>
> FileUtils.isActionPermittedForFileHierarchy checks if user has permissions
> for given action. The checks are made by impersonating the user.
> However, the listing of child dirs are done as the hiveserver2 user. If the
> hive user doesn't have permissions on the filesystem, it gives incorrect
> error that the user doesn't have permissions to perform the action.
> Impersonating the end user for all file operations in that function is also
> logically correct thing to do.
