Subject [jira] Commented: (HDFS-1150) Verify datanodes' identities to clients in secure clusters
Date Fri, 14 May 2010 23:35:43 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12867734#action_12867734
] 

Allen Wittenauer commented on HDFS-1150:
----------------------------------------

It appears the assumption is that the attacker won't be able to get root privileges.  I don't
think that's realistic for a complete fix and seems more of a security-through-obscurity approach.
 This is clearly a protocol problem and should be treated as such.  Doing TCP port slight
of hand isn't a real fix.

> Currently we use block access tokens to allow datanodes to verify clients' identities,
however we don't have a way for clients to verify the authenticity of the datanodes themselves.
