以下是Flume作为Agent实例，把应用数据发送到hdfs上，实现实时数据转发的功能。

example.conf: A single-node Flume configuration

Name the components on this agent

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

Describe/configure the source

a1.sources.r1.type = exec
a1.sources.r1.command = tail -f /var/log/secure

Describe the sink

a1.sinks.k1.type = logger
a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = hdfs://0.0.0.0:9000/ppp

Use a channel which buffers events in memory

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

Bind the source and sink to the channel

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