Flume 组件（source、channel、sink）远程调试

1.创建Maven工程

2.编写所需要自定义组件的代码（以Source为例）,打包放到服务器上

3.添加idea Debug 配置

4.在服务器上广播Debug端口

[atguigu@hadoop102 flume]$ export FLUME_JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005"

提示：这里需要将suspend=n，改为suspend=y.

5.启动Flume 程序，测试连接

[atguigu@hadoop102 flume ]$ flume-ng agent -c conf/ -f jobs/mysource.conf -n a1 -Dflume.root.logger=INFO,console

6.进入Idea 进行Debug操作

7.取消端口的广播

[atguigu@hadoop102 flume]$ export  -n FLUME_JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005"
