             Summary: Authenticating users from different realm without a trust relationship
                 Key: HADOOP-9296
                 URL: https://issues.apache.org/jira/browse/HADOOP-9296
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony


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
