> HeartbeatManager only processes one dead datanode (and failed storage) per round in heartbeatCheck(), that is to say, if there are ten failed storages, all datanode states need to be scanned 10 times, which is unnecessary. This patch makes the number of bad storages processed per scan configurable.
