Hadoop将本地文件复制到Hadoop文件系统

代码：

package com.hadoop;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URI;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IOUtils;
import org.apache.hadoop.util.Progressable;

public class FileCopyWithProgress {

	public static void main(String[] args) throws Exception {

		String localSrc = args[0];
		String dst = args[1];

		InputStream in = new BufferedInputStream(new FileInputStream(localSrc));

		Configuration config = new Configuration();
		FileSystem fs = FileSystem.get(URI.create(dst),config);

		OutputStream out = fs.create(new Path(dst),new Progressable() {

			@Override
			public void progress() {
				System.out.println(".");
			}
		});

		IOUtils.copyBytes(in, out, 4096, true);
	}
}
