Spark Structured Streaming 使用 python 和 Kafka 给出错误

Question

I am getting the below error when trying to initiate a readStream for kafka, my Kafka is up and running and I tested it multiple times to ensure it is processing. Kafka topic is created as well.

'''

kafka_df = spark.readStream \
        .format("kafka") \
        .option("kafka.bootstrap.servers", "localhost:9092") \
        .option("subscribe", "mytopic") \
        .option("startingOffsets", "earliest") \
        .load()

'''

Please deploy the application as per the deployment section of "Structured Streaming + Kafka Integration Guide".;

You need to import the kafka dependencies to run this, For pyspark. you can download the jar and put in spark/jars directory or import the dependencies in the sparkSession inital config, Please, follow this kafka-structured streaming docs
