telnet host ip
Event: { headers:{} body: 68 65 6C 6C 6F 0D hello. }
Event 是Flume 数据传输的基本单元
Event = 可选的header+byte array
Agent 选型:exec source +memory channel+logger sink
exex-memory-logger.conf
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source

技术选型:
exec source + memory channel + avro sink
avro source + memory channel + logger sink

先启动agent
flume-ng agent \
--name avro-memory-logger \
--conf conf $FLUME_HOME/conf \
--conf-file $FLUME_HOME/conf/avro-memory-logger.conf \
-Dflume.root.logger=INFO,console
再启动
flume-ng agent \
--name exec-memory-avro \
--conf conf $FLUME_HOME/conf \
--conf-file $FLUME_HOME/conf/exec-memory-avro.conf \
-Dflume.root.logger=INFO,console
