Since we are going to be connecting to the hadoop file system, we might as well test that as well.
因为我们要连接到hadoop文件系统，我们不妨测试。
14
One particularly handy aspect of Hadoop is that it handles the raw parsing of an input file, so that you can deal with one line at a time.
Hadoop可以对输入文件进行原始解析，这一点特别有用，这样您就可以每次处理一行。
15
For all the other settings, keep the defaults or choose the same values as you did for the Hadoop Master node.
对于所有其他设置，保留其默认值或者选择与HadoopMaster节点相同的值。
16
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。
17
Now that you have installed Hadoop and tested the basic interface to its file system, it's time to test Hadoop in a real application.
