索引 7 处的权限非法字符：hdfs://localhost:9000 与 hadoop
我正在尝试连接到 hdfs。
Configuration configuration = new Configuration();
configuration.set("fs.default.name", this.hdfsHost);
fs = FileSystem.get(configuration);
hdfsHost 为 127.0.0.1:9000。
但在 FileSystem.get(); 处得到此异常
我有另一个项目运行相同的代码，但运行良好。 有人可以提出任何建议吗？ 非常感谢您的

I am trying to connect to hdfs.
Configuration configuration = new Configuration();
configuration.set("fs.default.name", this.hdfsHost);
fs = FileSystem.get(configuration);
hdfsHost is 127.0.0.1:9000.
but get this exception at FileSystem.get();
I have another project running the same code, but works well.
Could anyone give any suggestion?
Thank you very much

尝试将 hdfsHost 作为合格的 url hdfs://127.0.0.1:9000 而不是 127.0.0.1:9000 传递
Try passing hdfsHost as a qualified url hdfs://127.0.0.1:9000 instead of 127.0.0.1:9000
如果 core-site.xml 中 hdfs 名称 (fs.defaultFS) 的属性值存在尾随空格，则可能会发生这种情况。
This can happen if there is trailing space in the core-site.xml against the property value for hdfs name (fs.defaultFS).
在 /etc/hosts 文件中将主机名与两个服务器（即客户端和服务器）中相应的 ip 绑定
Bind the host name with the corresponding ip in both the servers i.e. in both client and server in /etc/hosts file
