Question

当我部署Flink作业时，在ParserATNSimulator上收到以下递归错误，导致我的作业失败。这会导致堆栈溢出。是什么原因造成的？

职位详情：
我的工作图很简单input -> Map -> Filter -> Timestamps/Watermarks -> Map -> Filter。输入是一个KafkaConsumer至Avro反序列化模式的HashMap。映射运算符将哈希映射映射到自定义Event类。第二个地图函数是RichMapFunction，它存储着ValueState<PriorityQueue<Event>>。

部分堆栈跟踪：

由于递归调用ParserATNSimulator，Flink作业部署失败并出现StackOverflow错误
