一.自定义Sink的步骤
1>.编写自定义sink
2>.打包并将其发送到 /soft/flume/lib下
[yinzhengjie@s101 ~]$ cd /soft/flume/lib/ [yinzhengjie@s101 lib]$ rz [yinzhengjie@s101 lib]$ [yinzhengjie@s101 lib]$ ll | grep MyFlume -rw-r--r-- 1 yinzhengjie yinzhengjie 3398 Jun 20 18:12 MyFlume-1.0-SNAPSHOT.jar [yinzhengjie@s101 lib]$
3>.编写agent的配置文件
[yinzhengjie@s101 ~]$ more /soft/flume/conf/yinzhengjie_mysink.conf # Name the components on this agent a1.sources = r1 a1.sinks = k1 a1.channels = c1 # Describe/configure the source a1.sources.r1.type = netcat a1.sources.r1.bind = localhost a1.sources.r1.port = 8888 # Describe the sink a1.sinks.k1.type = cn.org.yinzhengjie.sink.MySink # Use a channel which buffers events in memory a1.channels.c1.type = memory a1.channels.c1.capacity = 100000 a1.channels.c1.transactionCapacity = 10000 # Bind the source and sink to the channel a1.sources.r1.channels = c1 a1.sinks.k1.channel = c1 [yinzhengjie@s101 ~]$
4>.启动flume并测试
a>.启动agent进程
[yinzhengjie@s101 ~]$ flume-ng agent -f /soft/flume/conf/yinzhengjie_mysink.conf -n a1 Warning: No configuration directory set! Use --conf <dir> to override. Warning: JAVA_HOME is not set!
