我正在尝试将Kafka主题导入spark dataframe，代码如下：

from pyspark.sql import SparkSession
from pyspark.sql.functions import *
from pyspark.sql.types import *

# Create a SparkSession
spark = SparkSession.builder \
    .appName("KafkaStreamToDataFrame") \
    .getOrCreate()

# Define the schema for the data in the Kafka stream
schema = StructType([
    StructField("key", StringType()),
    StructField("value", StringType())
])

# Read the data from the Kafka stream
df = spark \
    .readStream \
    .format("kafka") \
    .option("kafka.bootstrap.servers", "kafka_host:9092") \
    .option("subscribe", "ext_device-measurement_10121") \
    .load() \
    .selectExpr("CAST(key AS STRING)", "CAST(value AS STRING)") \
    .select(from_json(col("value"), schema).alias("data")) \
    .select("data.*")

# Start the stream and display the data in the DataFrame
query = df \
    .writeStream \
    .format("console") \
    .start()

query.awaitTermination()

我尝试使用spark-submit来执行代码：spark-submit --packages org.apache.spark:spark-sql-kafka-0-10_2.12:3.3.1 dev_ev.pySpark版本：3.3.1
尝试执行时出现以下错误：

不知道出了什么问题，Kafka的主题是可及的，并推动json记录。
尝试手动下载jar文件并将其保存在SPARK_HOME的jars目录中，然后使用以下命令执行：spark-submit --jars $SPARK_HOME/jars/org.apache.spark:spark-sql-kafka-0-10_2.12:3.3.1 dev_ev.py我希望显示 Dataframe 。
