Xuan Gong commented on YARN-1734:
---------------------------------
bq. Why is refreshAdminAcls() required to be done when transitioning state?
It is possible that previous active rm has updated the AdminAcls. In that case,
the current user may not have permission to do transitionToActive or
transitionToStandby. That is why I want to do the checking before transitioning
the state.
> RM should get the updated Configurations when it transits from Standby to
> Active
