--------------------------------

             Summary: Add option to list up allowed hosts that can do any 
operation to NameNode.
                 Key: HDFS-8613
                 URL: https://issues.apache.org/jira/browse/HDFS-8613
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.0
            Reporter: Kai Sasaki
            Assignee: Kai Sasaki
            Priority: Minor


Current NameNode receives all operations through client protocol from any 
hosts. 

However, some critical operations such as {{format}} should be restricted with 
not only Kerberos authentication but also with host names in order to prevent 
us from formatting NameNode by mistake. It is better to add option to write 
some allowed hosts which can do any operations to NameNode.
