Flume配置Replicating Channel Selector

1 官网内容

　　上面的配置是r1获取到的内容会同时复制到c1 c2 c3 三个channel里面

2 详细配置信息

　　

# Name the components on this agent
	a1.sources = r1
	a1.sinks = k1 k2
	a1.channels = c1 c2

	# Describe/configure the source
	a1.sources.r1.type = exec
	a1.sources.r1.command = tail -F /tmp/logs/cmcc.log

	# Describe the sink
	a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
	a1.sinks.k1.topic = cmcc1
	a1.sinks.k1.brokerList = hdp1:9092,hdp2:9092,hdp3:9092
	a1.sinks.k1.requiredAcks = 1
	a1.sinks.k1.batchSize = 20

	a1.sinks.k2.type = org.apache.flume.sink.kafka.KafkaSink
	a1.sinks.k2.topic = cmcc2
	a1.sinks.k2.brokerList = hdp1:9092,hdp2:9092,hdp3:9092
	a1.sinks.k2.requiredAcks = 1
	a1.sinks.k1.batchSize = 20

	a1.sinks.k2.type = org.apache.flume.sink.kafka.KafkaSink
	a1.sinks.k2.topic = cmcc2
	a1.sinks.k2.brokerList = hdp1:9092,hdp2:9092,hdp3:9092
	a1.sinks.k2.requiredAcks = 1
	a1.sinks.k2.batchSize = 20

	# Use a channel which buffers events in memory
	a1.channels.c1.type = memory
	a1.channels.c1.capacity = 1000
	a1.channels.c1.transactionCapacity = 100

	a1.channels.c2.type = file
	a1.channels.c2.checkpointDir = /tmp/flume/checkpoint
	a1.channels.c2.dataDirs = /tmp/flume/data

	# Bind the source and sink to the channel
	a1.sources.r1.channels = c1 c2

	# set channel for sinks
	a1.sinks.k1.channel = c1
	a1.sinks.k2.channel = c2
	 # #
	a1.sources.r1.selector.type = replicating
	 #

3 查看消费情况

　　

topic cmcc1的消费情况

	 	kafka-console-consumer.sh  --zookeeper hdp1:2181,hdp2:2181,hdp3:2181/kafka1.1.0  --topic cmcc1 --from-beginning
	Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].

 topic cmcc2的消费情况

4 总结
应该是启动了两次的原因，实际上是把文件重复两次的发送到了每个sink里面，实现了实验要求
