Kai Zheng commented on HADOOP-11754:
------------------------------------
bq.it would be good to preserve the existing RM behavior.
It's possible to remain the existing RM behavior if we just remove the
signature file property in RM when not in secure mode. In this way we don't
have to change the current logic in {{AuthenticationFilter}}, meanwhile not
having to bring the dirty codes in RM back. How do you like this way ? If
sounds good I can try the change.
