Flume-1.5.0+Kafka_2.9.2-0.8.1.1+Storm-0.9.2 分布式环境整合
# 整合场景
使用Flume监控指定目录，出现新的日志文件后将文件数据传到Kafka，最后由Storm从Kafka中取出数据并显示、、、
# Flume+Kafka的整合
# Flume的fks001.conf的配置文件
监控指定目录/usr/local/yting/flume/tdata/tdir1，然后使用自定义的Sink（com.yting.cloud.flume.sink.KafkaSink），将数据传入Kafka

这样Flume就算启动成功了，并且如果你的监控目录下出现新的日志文件的话，日志文件中的信息会传到Kafka中去，你懂的！
