Flume Netcat Source

1.cd /usr/local2/flume/conf

sudo vim netcat.conf

• # Name the components on this agent
• a1.sources = r1
• a1.sinks = k1
• a1.channels = c1
• # Describe/configure the source
• a1.sources.r1.type = netcat
• a1.sources.r1.bind = localhost
• a1.sources.r1.port = 8888
• # 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flume agent:
cd /usr/local2/flume/bin
soyo@soyo-VPCCB3S1C:/usr/local2/flume/bin$ ./flume-ng agent --conf conf -f /usr/local2/flume/conf/netcat.conf  --name a1
3.打开另一个shell：
nc localhost 8888
输入内容 即可以被flume捕获 

注意：flume 无论是netcat还是avro 都无法显示中文 需要到 **.conf中做配置，但Kafka默认是可以显示中文的
备注：这个问题在IDEA，spark Streaming 以flume为数据源的程序中 已经解决
