[jira] [Comment Edited] (TEZ-2583) Allow RecoveryService Pluggable
[ https://issues.apache.org/jira/browse/TEZ-2583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14609935#comment-14609935 ]

Attach patch.
* Make RecoveryService pluggable. Use RecoveryServiceWithEventHandlingHook for recovery system test. Although I can add hook to RecoveryService directly rather than doing it in RecoveryServiceWithEventHandlingHook, it is just for testing, so try to make change on RecoveryService as less as possible.
* 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.
