启动 flume agent：
# 先启动监听 avro 端口的 agent
# 在服务器 adp-03 上启动
$ flume-ng agent -n a3 -c conf -f a3.conf
# 在服务器 adp-01 上启动
$ flume-ng agent -n a1 -c conf -f a1.conf
# 在服务器 adp-02 上启动
$ flume-ng agent -n a2 -c conf -f a2.conf
在 adp-02 上发送数据：
[admin@adp-02 ~]$ nc localhost 44444
hello flume
在 adp-01 上写数据到文件中
[admin@adp-01 ~]$ echo hello flume > group.log
在 Flume 3 （adp-03） 上接收到全部数据：
[admin@adp-03 ~]
