修改配置文件：flume-conf.properties. 原来是10改为60直到100

# In this case, it specifies the capacity of the memory channel
agent.channels.c1.capacity =100

报错二： Cannot assign requested address

flume运行问题及测试

agent的source指定的端口：是安装flume的主机要监听的端口。IP是安装flume的主机的IP。

启动成功；

 

程序模拟：发送日志端

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;

public class FlumeWebLog {
    public static void main(String[] args)  {
        Socket client=null;
        try {
            client=new Socket("your flume address",6789);
            OutputStream outputStream = client.getOutputStream();
            Scanner scanner = new Scanner(System.in);
            PrintWriter pWriter = new PrintWriter(outputStream, true);
            pWriter.println("hello,enter bye to exit");
            String line = null;
            while (scanner.hasNextLine()) {
                if (!(line = scanner.nextLine()).equals("bye")) {
                    pWriter.println(line);
                    System.out.println(line);
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                client.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        
    }
}

把从控制台输入的内容发给flume。

运行，看到hdfs上面出现数据
