Review comment:
       You are right.. Looks like the permissions are inconsistent. With the change the default perm we use in `mkdirs` is 777 but `fs.getFileStatus(xxx).getPermission()` returns 751 for both internal and real dirs (regardless of whether we revert the change or not). I'm not sure why but I'll dig into this.
