Kai Sasaki created HDFS-8613: -------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
