Because the Hadoop master node communicates with slave nodes using SSH, you should set up an authenticated no-passphrase SSH connection between the master and slaves.
因为hadoop主节点使用SSH与从节点通信，所以应该在主节点和从节点之间建立经过身份验证的无密码的SSH连接。
It is assumed that the Hadoop slave node has been configured a priori in such a manner that it registers with the Hadoop master node.
这里假设Hadoop从节点已经在之前配置完成，也就是它已经注册到Hadoop主节点中。
Figure 14 shows the Hadoop Master instance and the two Hadoop Data node (slave) instances.

Based on this framework, the architecture of immersive online game is factored into game server, master node and slave nodes.
根据框架，沉浸式显示的网络游戏架构分为网络游戏服务器、主控节点和协从节点三个部分。
Since the slave nodes never listen to another slave response to the master, a slave node cannot reply incorrectly to another slave node.
因为从节点从不收听其它从节点而只对主节点作为出响应，从节点不能错误地对其它从节点作出应答。
The network Master (typically a PLC) recognizes the slave node by means of this address.
