【问题描述】:
我只是找不到这个问题的任何答案:
[hadoop@evghost ~]$ start-dfs.sh 15/10/21 21:59:17 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured. Starting namenodes on [] evghost: ssh: connect to host evghost port 22: Connection refused evghost: ssh: connect to host evghost port 22: Connection refused Starting secondary namenodes [0.0.0.0] Error: Please specify one of --hosts or --hostnames options and not both. 15/10/21 21:59:20 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
有人知道解决办法吗?

Namenode 无法连接datanode。尝试使用 ssh 从 nn 连接到 dn。可能是网络禁用或过载。

好的,我试试。谢谢。
