Kai Zheng commented on HADOOP-11754:
------------------------------------
It sounds complete ! Just note for the 2nd way, to allow RM to fall back to
RandomSigner, we can unset or remove the file property. Current
AuthenticationFilter will perform the fallback when not seeing the file
property. We don't have to bring back the original specific codes in RM.
> RM fails to start in non-secure mode due to authentication filter failure
