Alejandro Abdelnur commented on HADOOP-9296:
--------------------------------------------

I get that with RPC we have more flexibility. But ...., wouldn't be a good thing o be consistent

> 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
