a1.sources = r1
a1.sinks = k1
a1.channels = c1

Describe/configure the source

a1.sources.r1.type = cn.csn.flume.source.TailFileSource
a1.sources.r1.filePath = /bigdata/logs/access.log
a1.sources.r1.offsetFile = /bigdata/offset.txt
a1.sources.r1.interval = 1000
a1.sources.r1.charset = UTF-8

Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

Describe the sink

a1.sinks.k1.type = logger

Bind the source and sink to the channel

a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
