Binglin Chang commented on HADOOP-9912:
---------------------------------------
bq. If the NN resolves links it allows the user to unexpectedly access stuff
outside the mount point.
Your comments reminds me another potential issue about permission checking.
How to handle permission denied in listStatus if some(not all) of its entry is
permission denied? getFileStatus doesn't have this issue because it is either
success or failed.
I did a check and found out, it just simply skip the symlink, I think it is not
the right.
