rocketmq-flume Source&Sink

该项目用于RocketMQ与Flume-ng之间的消息接收和投递。

1. 首先请确定您已经对RocketMQ和Flume-ng有了基本的了解
2. 确保本地maven库中已经存在RocketMQ相关的包，或者下载RocketMQ源码自行编译
3. 在rocketmq-flume项目根目录执行mvn clean install dependency:copy-dependencies
4. 将rocketmq-flume相关依赖jar包拷贝到$FLUME_HOME/lib目录中(具体包会在后面描述)

agent1.sources.source1.type=avro
agent1.sources.source1.bind=0.0.0.0
agent1.sources.source1.port=15151
agent1.sources.source1.channels=channel1

agent1.sinks.sink1.type=com.handu.flume.sink.rocketmq.RocketMQSink
agent1.sinks.sink1.namesrvAddr=rocketmq_namesrv:9876
agent1.sinks.sink1.producerGroup=MyProducerGroup_1
agent1.sinks.sink1.topic=FromFlume
agent1.sinks.sink1.tag=Tag1

agent1.channels.channel1.transactionCapacity=100
agent1.channels.channel1.keep-alive=3

• 将下面jar包拷贝到$FLUME_HOME/lib目录中

rocketmq-flume-sink-1.0.0.jar (文件位置: $PROJECT_HOME/rocketmq-flume-sink/target)
fastjson-1.1.41.jar (文件位置: $PROJECT_HOME/rocketmq-flume-sink/target/dependency)
netty-all-4.0.23.Final.jar (文件位置: $PROJECT_HOME/rocketmq-flume-sink/target/dependency)

rocketmq-remoting-3.2.2.jar (文件位置: $PROJECT_HOME/rocketmq-flume-sink/target/dependency)

• 执行测试命令查看

shell1> $FLUME_HOME/bin/flume-ng agent -c conf -f conf/flume.conf -n agent1 -Dflume.root.logger=INFO,console
shell2> $FLUME_HOME/bin/flume-ng avro-client -H localhost -p 15151 -F $FLUME_HOME/README

• 查看shell1控制台输出的信息
