该项目用于RocketMQ与Flume-ng之间的消息接收和投递。
- 首先请确定您已经对RocketMQ和Flume-ng有了基本的了解
- 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
- 在rocketmq-flume项目根目录执行
mvn clean install dependency:copy-dependencies - 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)
| 配置项 | 必填 | 默认值 | 说明 |
|---|---|---|---|
| namesrvAddr | 必填 | null | Name Server地址，遵循RocketMQ配置方式 |
| producerGroup | 可选 | DEFAULT_PRODUCER | Producer分组 |
| topic | 必填 | null | Topic名称 |
| tags | 可选 | 空字符串 | Tag名称，遵循RocketMQ配置方式 |
- 编写Flume的配置文件

- 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
