Question

我正在尝试整合Kafka和Spark。我在Kafka创建了一个制作人我想在Spark集群中使用消息。

我使用以下命令进行火花作业提交，但是它给出了错误。你可以帮我解决这个错误吗？看来我错过了一些相关的jar文件。

我目前的火花版本：2.1.1.2.6.2.0-205

Python版本：2.7.5

Python脚本：

import sys

import os 

from pyspark import SparkContext, SparkConf

from pyspark.streaming import StreamingContext

from pyspark.streaming.kafka import KafkaUtils

if __name__ == "__main__":

    conf = SparkConf().setMaster("local").setAppName("Spark-Kafka Integration")

    sc = SparkContext(conf = conf)

    ssc = StreamingContext(sc, 2)

    lines = KafkaUtils.createStream(ssc,'localhost:2181','raw-event-streaming-
    consumer',{'NewTopic':1}) 

    print(lines)

    ssc.start()

    ssc.awaitTermination()

错误日志：
