驗證：
1. 首先啟動HDFS和kafka
2. 創建topic
kafka-topics.sh --create --zookeeper master:2181,slave1:2181,slave2:2181 --replication-factor 1 --partitions 1 --topic kafkatest
啟動flume以及測試
3. 啟動Flume
服務端 /usr/local/flume/bin/flume-ng agent -f flume-exec-total.conf -n agent -Dflume.root.logger=INFO, console 客戶端 echo "wangzai doubi" > test.log
4. 啟動kafka客戶端
/usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper master:2181,slave1:2181,slave2:2181 --topic kafkatest --from-beginning
結果如圖：
Flume服務端：
HDFS：
Kafka客戶端：
