KafkaUtils 包属于传统的 Spark Streaming，而您正在尝试使用 Spark Structured Streaming 中的 Kafka 支持。
实际上，在 2023 年使用传统的 Spark Streaming 是没有必要的。只需按照文档中的说明访问 Kafka 中的数据。
df = spark \
.readStream \
.format("kafka") \
.option("kafka.bootstrap.servers", "host:port") \
.option("subscribe", "my_topic") \
.load()
英文:
The KafkaUtils package belongs to the legacy Spark Streaming, while you're trying Kafka support in Spark Structured Streaming.
Really, there should be no reason to use legacy Spark Streaming in 2023rd. Just access data in Kafka as described in the documentation.
df = spark \
.readStream \
.format("kafka") \
.option("kafka.bootstrap.servers", "host:port") \
.option("subscribe", "my_topic") \
.load()
