-----------------------------------------
Hi [~bibinchundatt],
Thanks for the patch, test cases ran fine, approach and test case seems to be
fine but few comments from my side
# timeout of 900000 is on the higher side is that much req or was it for local
testing ?
# instead of test case in RMHA can we think of adding it to TestRMAdminService
as the failure is related to transition to Active ?
# May be while throwing RMFatalEvent better to wrap it with another exception
wrapping the existing one and with the message that transition to active failed
so that RM Logs have clear information on what operation it exited. or may be
eventType instead of having {{ACTIVE_REFRESH_FAIL}} we can have more intuitive
name {{TRANSITION_TO_ACTIVE_FAILED}}
> Both RM in active state when Admin#transitionToActive failure from refeshAll()
