验证：
1. 首先启动HDFS和kafka
2. 创建topic
kafka-topics.sh --create --zookeeper master:2181,slave1:2181,slave2:2181 --replication-factor 1 --partitions 1 --topic kafkatest
启动flume以及测试
3. 启动Flume
服务端 /usr/local/flume/bin/flume-ng agent -f flume-exec-total.conf -n agent -Dflume.root.logger=INFO, console 客户端 echo "wangzai doubi" > test.log
4. 启动kafka客户端
/usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper master:2181,slave1:2181,slave2:2181 --topic kafkatest --from-beginning
结果如图：
Flume服务端：
HDFS：
Kafka客户端：
