Hitesh Shah commented on TEZ-2779:
----------------------------------

[~Sreenath] Does the UI support a config which takes in a list of RM hostnames? 
If not, let us consider this scenario: 

   - Tez UI config has rm1 as the hostname for the RM. 
   - YARN has RM HA enabled with rm1, rm2 and rm3 as the hosts. 
   - rm1 is completely down but rm2 and rm3 are up. 



> When ResourceManager is HA mode, How can I set up Tez UI configs?
