Apache kafka 将Storm 1 Kafka拓扑转换为Heron，有几个问题

正在尝试将Storm 1.0.6拓扑切换到Heron。一步一步地把卡夫卡的壶嘴移开，看看事情进展如何。主要方法如下（从原始通量版本修改）：

相关POM条目：

        <dependency>
            <groupId>org.apache.heron</groupId>
            <artifactId>heron-api</artifactId>
            <version>0.20.3-incubating</version>
        </dependency>

        <dependency>
            <groupId>org.apache.heron</groupId>
            <artifactId>heron-storm</artifactId>
            <version>0.20.3-incubating</version>
        </dependency>

        <dependency>
            <groupId>org.apache.storm</groupId>
            <artifactId>storm-kafka</artifactId>
            <version>1.0.6</version>
        </dependency>

问题1:拓扑立即退出，是否有相当于Flux'--sleep'的Eco标志使其运行一段时间（以进行调试等）

问题2:我有点惊讶于我需要加入storm kafka（本以为会有一个Heron等价物）-这是正确的（或其他神器）吗？如果是，1.0.6是可以使用的版本，还是Heron与另一个版本配合更好

问题3:以上是YAML中的

类型：“storm”

，尝试

类型：“heron”

会出现以下错误：

INFO: Building spouts
Exception in thread "main" java.lang.ClassCastException: class org.apache.storm.kafka.KafkaSpout cannot be cast to class org.apache.heron.api.spout.IRichSpout (org.apache.storm.kafka.KafkaSpout and org.apache.heron.api.spout.IRichSpout are in unnamed module of loader 'app')

这就是它使用卡夫卡的方式，类型需要是风暴而不是苍鹭，或者这里有一些解决方法吗

• 有好几条卡夫卡给苍鹭的嘴。我使用Storm（Storm-kafka-client-2.1）克隆并在生产中使用它

---

问题1

：我不确定拓扑为什么会关闭。尝试使用

--verbose

标志运行提交。此时，

--sleep

参数的功能不存在。如果你需要的话，它可以是一个功能

问题2

：有一只苍鹭。在Heron被捐赠给Apache之后，为了发布二进制版本，需要做大量的工作。大部分工作已经完成。在下一个版本中，我希望所有二进制工件都能被适当地分发

问题3

：出现此问题的原因是，根据指定的类型，它在某个包中查找螺栓/喷嘴。当输入“storm”时，它希望它实现或扩展的类是“org.apache.storm”。当输入“heron”时，它希望它实现或扩展的类是“org.apache.heron”。如果使用依赖项storm kafka，则类型必须为“storm”。在这里可以找到与苍鹭相当的物种
