Jason Lowe commented on YARN-3895:
----------------------------------

Thanks for the detailed writeup, Vrushali!

I am a bit confused about the application_id column for a domain table entry.  
What if the domain doesn't apply to the entire application (i.e.: just to one 
DAG within a multi-DAG app) or what if a domain applies to more than one 
application?  Tez does not use a domain across applications, but I'm curious if 
this design will preclude a domain crossing applications (e.g.: a domain is 
setup for an entire Oozie flow, and all applications in that flow use that one 
domain for ACLs).
