先啟動avro-memory-logger.conf  wang-one啟動

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

再啟動exec-memory-avro.conf  wang-two啟動

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