Flume-ng-extends的应用

目的: 这个可以tail dir 文件，监听文件目录写入事件，只要往这个目录写入文件就能触发

首先需要flume-ng-extends：从获取源代码 https://github.com/jinoos/flume-ng-extends，maven编译打包

将flume-ng-extends-0.0.1-SNAPSHOT.jar,另外还要下载commons-vfs2-2.0.jar这个jar包（这个不然可能会报错）一起放到flume的lib下

2，agent配置

[html]view plaincopy 
   
 hadoop@stormspark:~/bigdata/flume-1.4.0-bin/dirTailTest$ cat ../conf/flume-ng-extend.properties   
 a.sources = sources  
 a.sinks = sinks  
 a.channels = c  
   
 #configure sources  
 a.sources.sources.type = com.jinoos.flume.DirectoryTailSource  
 a.sources.sources.dirs = s0 s1  
 a.sources.sources.dirs.s0.path = /home/hadoop/bigdata/flume-1.4.0-bin/dirTailTest/s0in  
 a.sources.sources.dirs.s1.path = /home/hadoop/bigdata/flume-1.4.0-bin/dirTailTest/s1in  
 #congfigure sinks  
 a.sinks.sinks.type = logger  
 #configure channals  
 a.channels.c.type = memory  
 #bind channel  
 a.sources.sources.channels = c  

启动这个agent

[html]view plaincopy 
   
 bin/flume-ng agent --conf conf  --conf-file conf/flume-ng-extend.properties --name a -Dflume.root.logger=INFO,console  

然后往s0in,s1in目录丢进去一些文件

[html]view plaincopy 
   
 cp ../conf/*.properties  ./s1in/  

可以看到已经触发了

[html]view plaincopy
