storm hdfs螺栓不工作

所以我刚开始研究storm并试图理解它。我正在尝试连接到Kafka主题，读取数据并将其写入hdfs。起初，我创建它时没有使用ShuffleGroup（“stormspout”），我的StormUI显示spout正在使用来自主题的数据，但没有任何内容写入到bolt（除了它在hdfs上创建的空文件）。然后我添加了shufflegrouping（“风暴喷口”）；现在，螺栓似乎出现了一个错误。如果有人能帮上忙，我会非常感激的。
谢谢，科尔曼

首先，尝试从execute方法发出值，如果您是从不同的工作线程发出，那么让所有工作线程向linkedblockingqueue中提供数据，并且只有一个工作线程允许从linkedblockingqueue发出值。
其次，尝试将config.setmaxpoutpending设置为某个值，然后再次尝试运行代码，并检查场景是否持续，尝试减小该值。
reference-config.topology\u max\u spout\u pending：设置一次可以挂起单个喷口任务的最大喷口元组数（pending表示元组尚未确认或失败）。强烈建议您设置此配置以防止队列爆炸。

我最终通过浏览storm源代码找到了答案。
我没准备好

RecordFormat format = new DelimitedRecordFormat().withFieldDelimiter("|");

包括它

builder.setBolt("stormbolt", new HdfsBolt()
                                      .withFsUrl("hdfs://192.168.134.137:8020")//54310
                                 .withSyncPolicy(syncPolicy)
                                 .withRecordFormat(format)
                                 .withRotationPolicy(rotationPolicy)
                                 .withFileNameFormat(fileNameFormat),1
                    ).shuffleGrouping("stormspout");

在hdfsbolt.java类中，它尝试使用它，如果没有设置它，基本上就会失败。这就是npe的来源。
希望这对其他人有所帮助，确保你已经设置了本课程所需的所有位。一个更有用的错误消息，如“recordformat not set”会很好。。。。
