> 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 and a
> waste of resources. This patch makes the number of bad storages processed per
> scan configurable.
