[jira] [Commented] (HADOOP-9296) Authenticating users from
different realm without a trust relationship
[ https://issues.apache.org/jira/browse/HADOOP-9296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633485#comment-13633485 ]
Benoy Antony commented on HADOOP-9296:
--------------------------------------
To solve this problem, I am trying to add ability to plugin custom Authentication in Hadoop(HADOOP-9479). This allows us to keep our custom logic internally.

> Hadoop Masters (JobTracker and NameNode) and slaves (Data Node and TaskTracker) are part of the Hadoop domain, controlled by Hadoop Active Directory.
> The users belong to the CORP domain, controlled by the CORP Active Directory.
> In the absence of a one way trust from HADOOP DOMAIN to CORP DOMAIN, how will Hadoop Servers (JobTracker, NameNode) authenticate CORP users ?
> The solution and implementation details are in the attachement
