+ <description>ACL for the admins, this configuration is used to control
+ who can access the default servlets in the namenode, etc. The value
+ should be a comma separated list of users and groups. The user list
+ comes first and is separated by a space followed by the group list,
+ e.g. "user1,user2 group1,group2". Both users and groups are optional,
+ so "user1", " group1", "", "user1 group1", "user1,user2 group1,group2"
+ are all valid (note the leading space in " group1"). '*' grants access
+ to all users and groups, e.g. '*', '* ' and ' *' are all valid.
