Jeff Zhang commented on TEZ-2583:
---------------------------------
Attach patch.
* Make RecoveryService pluggable. Use RecoveryServiceWithEventHandlingHook for
recovery system test.
* In RecoveryServiceWithEventHandlingHook allow hook to log recovery event and
summary event so that we can control when to shutdown AM.
* SimpleRecoveryEventHook is only for shutting down AM based on the current
recovery event. We can implement other hook for more complicated case which may
involve both recovery event & summary event.
* TestRecovery has 2 simple examples to illustrate how to do recovery system
test. I will make them ingorable now because they will cost losts of time.
