A heartbeat message and subtask oriented fault tolerance policy were also used which can achieve the reliability.
自愿机端的心跳消息和面向子任务的容错方式可以达到可靠性高的效果。
It emphasizes adaptive heartbeat message detection, dual-software design and background data synchronization, and demonstrates how to apply the high-reliability system.
文中着重论述了自适应心跳信息检测、软双工设计和背景数据同步，实现了应用软件的高可靠性。
Failure to respond to a heartbeat message is caused by several events, such as computer failure, network interface failure, network failure, or even periods of unusually high activity.
未能对检测信号消息做出响应是由几个事件导致的，例如计算机失败、网络接口失败、网络失败，甚至是很少见的高活动期间。
The NameNode detects this condition by the absence of a Heartbeat message. The NameNode marks DataNodes without recent Heartbeats as dead and does not forward any new IO requests to them.
Namenode通过心跳包的缺失检测到这一情况，并将这些Datanode标记为dead，不会将新的IO请求发给它们。
The heartbeat algorithm is optimized and only sent if needed (for example, if the members are already communicating for other reasons, there is no need to send an additional heartbeat message).
检测信号算法经过优化，且仅在需要时发送该信号（例如，如果成员已经因其他原因处于通信中，就没有必要再发送一条检测信号消息）。
