我正在学习 Hadoop，这让我发疯了！我能做些什么？

SocketException: invalid paramemter尝试从另一台主机连接到 HDFS NameNode 时，我遇到了同样的错误 ( )。

如果您能够bin/hadoop fs -ls /在 NameNode 上运行，那么您应该检查/etc/hosts客户端主机（或运行 DataNode 的主机）。在您的情况下，查找“ 127.0.0.1 youcheng1-OEM”行。我通过添加以下行解决了我的问题：

#127.0.0.1 youcheng1-OEM
127.0.0.1 localhost
192.168.1.192 youcheng1-OEM

Hadoop 似乎解析youcheng1-OEM为127.0.0.1并将其传递给sun.nio.ch.SocketChannelImpl.connect(...).

将以下行添加到您的/etc/hosts文件中

0.0.0.1 localhost
