kafka-storm-starter是一个展示如何实现Apache Kafka与Apache Storm的集成案例,使用Apache Avro作为数据序列化。

运行$ ./sbt test
可以对 Kafka Storm和Kafka-Storm 集成进行端到端的测试。

运行$./sbt run
这个命令是加载运行KafkaStormDemo,这个演示源码能够在内存中启动ZooKeeper Kafka和Storm实例,然后运行Storm topology 连接和读取Kafka实例。

会看到如下输出:
7031 [Thread-19] INFO backtype.storm.daemon.worker - Worker 3f7f1a51-5c9e-43a5-b431-e39a7272215e for storm kafka-storm-starter-1-1400839826 on daa60807-d440-4b45-94fc-8dd7798453d2:1027 has finished loading

这表示Storm已经连接上Kafka。
