Question

我是Spark的新手，我想为Spark创建结构化的流，以读取和显示kafka主题的消息。我在sample.py文件中编写了以下内容：

from pyspark.sql import SparkSession
from pyspark.sql.functions import explode
from pyspark.sql.functions import split
import os

os.environ['PYSPARK_SUBMIT_ARGS'] = '--packages org.apache.spark:spark-sql-kafka-0-10_2.12:2.4.4 pyspark-shell'
spark = SparkSession.builder.appName("StructuredNetworkWordCount").getOrCreate()


df = spark.readStream.format("kafka").option("kafka.bootstrap.servers","localhost:9092").option("subscribe", "testKafka").option("startingOffsets", "earliest").load()
df.printSchema()
df.selectExpr("CAST(key AS STRING)", "CAST(value AS STRING)")

并且我将spark-sql-kafka文件放在/ usr / local / spark内的jars文件夹中。我通过写来运行此：spark-submit --packages org.apache.spark：spark-sql-kafka-0-10_2.12：2.4.4 sample.py但这给了我错误：

谁能告诉我为什么。我被困在这里两天了。预先感谢。

您需要拥有

1. 已安装Scala 2.12
2. 已下载火花2.4.4

然后2.4.4_2.12的软件包应该可以正常工作
