Kai Sasaki created HADOOP-12102: ----------------------------------- Summary: Add option to list up allowed hosts that can do any operation as generic ACL. Key: HADOOP-12102 URL: https://issues.apache.org/jira/browse/HADOOP-12102 Project: Hadoop Common 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. Although originally this is about HDFS daemons, this feature should be implemented as one of generic ACL. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
