配置文件简单例子

#define
agent1.sources = source1
agent1.channels = channel1
agent1.sinks = sink1 sink2

#Describe the source
agent1.sources.source1.type = exec
agent1.sources.source1.command = tail -F /srv/apps/taskworker/log/taskworker.log
agent1.sources.source1.interceptors=e1
agent1.sources.source1.interceptors.e1.type=timestamp

#Describe the sink
agent1.sinks.sink1.type = avro
agent1.sinks.sink1.hostname= 10.4.1.100
agent1.sinks.sink1.port = 10000

#Describe the channnel
agent1.channels.channel1.type = file
agent1.channels.channel1.checkpointDir = /home/dongxiao.yang/checkpoint
agent1.channels.channel1.dataDirs = /home/dongxiao.yang/data

#Bind the source and sink to the channel
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channel = channel1
agent1.sinks.sink2.channel = channel1
