Amareshwari Sriramadasu commented on HADOOP-6862:
-------------------------------------------------
I think adding/removing a wild card character through this api should not be
allowed, because adding a '*' (the only allowed wild card character in ACL) to
an already created ACL does not make sense. Also, It makes sense to accept it
only in the constructor as it is now, which defines the behavior to be simple.
For example, adding it twice by addUser('*") and removing it by removeUser("*")
once would result in allowing all the users.
I will submit a patch which throws an exception saying "wild card not allowed"
if a wild card character is passed.
Thoughts?
