It emphasizes adaptive heartbeat message detection, dual-software design and background data synchronization, and demonstrates how to apply the high-reliability system.
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 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.
医生通常会检查他们的呼吸情况、心跳、耳朵、眼睛和咽喉，还会测量体重、取病人的尿样进行检测，同时还会查找可能患严重疾病的征兆。
Doctors check their breathing, heartbeat, ears, eyes, and throat, their weight, take samples of patient's fluids to run tests, and look for signs of more serious illnesses.
