Kevin Risden reopened KNOX-1642:
--------------------------------

Ok so now it reproduces again - ugh. Trying to figure out what is happening. I think it only happens in the case of Knox starting and the first url RM being standby.

> Currently if there are multiple RM URLs defined for YARNUI or YARNUIV2 and the first one is not active, there is a redirect loop that causes issues. If the first URL is active then there is no issue and YARN UI works correctly. 
> Work Around: Restart active RM to force failover to other RM.
