Hadoop 2.7.3：配置错误：未配置namenode地址dfs.namenode.servicerpc-address或dfs.namenode.rpc-address

Question

我有三台机器centOS 7，我想部署hadoop 2.7.3。

我收到以下错误：

[root@hadoop-master hadoop]# sbin/start-dfs.sh
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
Starting namenodes on []
cat: /opt/hadoop/hadoop/slaves: No file ou folder found
sed: -e expression n°1, caracter 6: option unknown pour `s'
Starting secondary namenodes [0.0.0.0]

我查了很多网站，但它并没有解决我的问题。有没有人有想法？

有关信息，请参阅我的mxl文件：
