1. node3 上创建配置文件 option3

# example.conf: A single-node Flume configuration 
# Name the components on this agent 
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source 
a1.sources.r1.type = avro
a1.sources.r1.bind = node3
a1.sources.r1.port = 10086
# Describe the sink 
a1.sinks.k1.type = logger 
# Use a channel which buffers events in memory 
a1.channels.c1.type = memory 
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100 
# Bind the source and sink to the channel 
a1.sources.r1.channels = c1 
a1.sinks.k1.channel = c1 

2. 启动 node3 上 flume

[root@node3 ~]# flume-ng agent -n a1 -conf-file option3 -Dflume.root.logger=INFO,console

3. 运行项目源码
