storm报错：Exception in thread "main" java.lang.RuntimeException: InvalidTopologyException(msg:Component: [mybolt] subscribes from non-existent stream: [default] of component [kafka_spout])

问题描述：

　　storm版本：1.2.2，kafka版本：2.11。

　　  在使用storm去消费kafka中的数据时，发生了如下错误。

报错图示如下：

报错的意思为：mybolt这个组件，在从kafka_sput组件上消费消息时，它所消费的default数据流是不存在的。

上面的报错是因为代码中有地方写错了，下面贴出代码

1）KafkaTopoDemo类（main方法入口类和kafkaSpout设置）

错误出现在KafkaTopoDemo类中，已在上面的代码中做了黄色高亮标注。

错误的原因在于，在代码中对RecordTranslator进行设置时（第67行），将数据流Id设置成了stream1；而在对topologyBuilder设置bolt时（第32行），使用的分发策略是shuffleGrouping("kafka_spout")，其实错误跟分发策略没关系，但是跟分发策略的使用方式有关系——当使用shuffleGrouping(String componentId)这种方式设置分发策略时，mybolt组件默认是从上游组件的default 这个数据流中获取数据，而在代码中，我已将上游（kafka_spout）的数据流id设置成了stream1，故而导致了报错（InvalidTopologyException(msg:Component: [mybolt] subscribes from non-existent stream: [default] of component [kafka_spout])，说default数据流不存在）。

因此，需要对代码做了相应修改，即：在设置mybolt组件的分发策略时，使用shuffleGrouping(String componentId, String streamId)，手动指定要读取的数据流id为stream1，如此，程序就不会报该错误了。

topologybuilder.setBolt("mybolt", new MyBolt("/tmp/storm_test.log")).shuffleGrouping("kafka_spout", "stream1");
