我有一个三节点 hadoop 集群正在运行。出于某种原因，当数据节点从属设备启动时，它们会使用我的网络上甚至不存在的 IP 地址来识别。这是我的主机名和 IP 映射。
nodes:
- hostname: hadoop-master
ip: 192.168.51.4
- hostname: hadoop-data1
ip: 192.168.52.4
- hostname: hadoop-data2
ip: 192.168.52.6
正如您在下面看到的，hadoop-master 节点正常启动，但在其他两个节点中，只有一个显示为 Live 数据节点，并且无论哪个显示始终具有 IP 192.168.51.1，如您在上面看到的我的网络上什至不存在。

我确实尝试为每个主机显式添加 dfs.datanode.address，但在这种情况下，它甚至无法显示为活动节点。这是我的 hdfs-site.xml 的样子（注意我已经尝试过设置 dfs.datanode.address 和不存在）。

为什么 hadoop 将每个数据节点与一个甚至不存在的 IP 相关联？或者更重要的是，我怎样才能让节点正常运行？
更新：所有节点上的文件 /etc/hosts 是相同的
192.168.51.4 hadoop-master
192.168.52.4 hadoop-data1
192.168.52.6 hadoop-data2
以下是我的奴隶文件的内容。
hadoop@hadoop-master:~$ cat /usr/local/hadoop/etc/hadoop/slaves
hadoop-master
hadoop-data1
hadoop-data2
