防火墙已经关闭，hosts文件中主机名配置的是内网IP
先放代码：
```java
@Test
publicvoidtestCopyFromLocalFile()throwsIOException,InterruptedException,URISyntaxException{
//1获取文件系统
Configurationconfiguration=newConfiguration();
FileSystemfs=FileSystem.get(newURI("hdfs://47.101.*.*:9000"),configuration,"root");
//2上传文件
fs.copyFromLocalFile(newPath("G:/hello.txt"),newPath("/hello2.txt"));
//3关闭资源
fs.close();
System.out.println("over");
}
```
