Xiao Chen commented on HDFS-7087:
---------------------------------

Hi [~andrew.wang],

Thanks for reporting the issue and further explain it in the comment. 
I'm working on this JIRA, and have a few points I want to clarify.

When listing {{/.reserved}}, we will be able to see hard-coded FileStatuses of {{/.reserved/.inodes}}
and {{/.reserved/raw}}:
1. Is this visible to all users? Or just the superuser? Does it make sense if I set the permission
as 755?
2. What atime and mtime would be preferred? I know they aren't supposed to be modified. But
I'm not sure when {{ls}} it, what timestamp would be meaningful for them.

It seems like we should be able to list /.reserved to see them.
