只需使用
FileSystem的copyFromLocalFile方法即可。如果源路径是本地目录，它将被复制到HDFS目标：
...Configuration conf = new Configuration();conf.addResource(new Path("/home/user/hadoop/conf/core-site.xml"));conf.addResource(new Path("/home/user/hadoop/conf/hdfs-site.xml"));FileSystem fs = FileSystem.get(conf);fs.copyFromLocalFile(new Path("/home/user/directory/"), new Path("/user/hadoop/dir"));...
