--------------------------------------

I am reopening this issue to backport the fix to branch-2.

Please shout out if you think this is incompatible change (e.g. downstream 
applications that depends on existing semantics). Thanks.

> FsPermissions's string constructor breaks on valid permission strings, like 
> "1777". 
> This is because FsPermission class naïvely uses UmaskParser to do it’s 
> parsing of permissions: (from source code):
> public FsPermission(String mode) {
>     this((new UmaskParser(mode)).getUMask());
> }
> The mode string UMask accepts is subtly different (esp wrt sticky bit), so 
> parsing Umask is not the same as parsing FsPermission.
