利用Eclipse对Flume进行远程调试分析环境搭建

Posted 2022-04-30 yangcx666

准备工作：

1、到Flume官网下载apache-flume-1.8.0-bin.tar.gz

2、下载代码：https://github.com/javabigdataxin/FlumeExtend

 

在Flume的conf目录新建一个RollingFileSink.conf文件

a1.sources = r1

a1.sinks = k1

a1.channels = c1

# 配置sources

a1.sources.r1.type = netcat

a1.sources.r1.bind = localhost

a1.sources.r1.port = 6666

# 配置sink

a1.sinks.k1.type = com.flumeextend.RollingFileSink

a1.sinks.k1.sink.directory = G:\\apache-flume-1.8.0-bin\\RollingFileSinkTest

a1.sinks.k1.sink.rollInterval=0

a1.sinks.k1.sink.batchSize=100

a1.sinks.k1.sink.serializer=TEXT

a1.sinks.k1.sink.serializer.appendNewline = true

# 配置channel

a1.channels.c1.type = file

a1.channels.c1.checkpointDir = G:\\apache-flume-1.8.0-bin\\checkpoint

a1.channels.c1.dataDirs = G:\\apache-flume-1.8.0-bin\\data

# 将三者串联

a1.sources.r1.channels = c1

a1.sinks.k1.channel = c1

 

开启FLume远程调试：

在bin目录下的flume-ng.ps1文件，增加以下配置：

$JAVA_OPTS="-Xmx100m -Xdebug -Xrunjdwp:transport=dt_socket,address=8888,server=y,suspend=y"

 

 

打开CMD命令行，执行以下命令，启动Flume Agent：

cd G:\apache-flume-1.8.0-bin\bin

.\flume-ng.cmd agent --conf ../conf  --conf-file ../conf/RollingFileSink.conf --name a1 --property flume.root.logger=INFO,console

 

会出现：Listening for transport dt_socket at address: 8888

 

到Eclipse中开启flume远程调试：

 

打好断点：

 

点击Debug，就可以开始调试我们自己写的Flume插件了：

 

使用telnet给Flume发送一个event

 

新打开一个终端，输入命令：

telnet localhost 6666

 

 

在Eclipse中先打好断点：

 

 

输入Hello World，之后可以在Eclipse中打断点调试啦！
