为什么Hadoop name节点连接到奇怪的[aca8ca1d.ipt.aol.com]主机名？

Question

我正在使用mac系统并启动hadoop系统，使用以下命令：

start-dfs.sh

并且我的主机名是“hostname”命令返回的“ctpllt072.local”。但当连接启动name节点时,我会得到一个奇怪的主机名和消息,如下所示：

Starting namenodes on [aca8ca1d.ipt.aol.com]
aca8ca1d.ipt.aol.com: ssh: connect to host aca8ca1d.ipt.aol.com port 22: Operation timed out

因此将配置更改为

<configuration>
   <property>
      <name>fs.defaultFS</name>
      <value>hdfs://192.168.***.***/</value>
   </property>
</configuration>
