Guanghao Zhang commented on HBASE-20524:
----------------------------------------
Checked all methods which call removeRecoveredSource or removeSource will call
terminate first. So move clear metrics to terminate method. But there was a
special case for RevoeredReplicationSource. It will call removeRecoveredSource
in tryFinish method. So clear metrics in this method, too.
