看了其他答案后，我还是想不出来。
我能够使用kafkaproducer和kafkaconsumer从我的笔记本中发送和接收消息。

producer = KafkaProducer(bootstrap_servers=['127.0.0.1:9092'],value_serializer=lambda m: json.dumps(m).encode('ascii'))
    consumer = KafkaConsumer('hr',bootstrap_servers=['127.0.0.1:9092'],group_id='abc' )

我尝试用spark上下文和spark会话连接到流。

from pyspark.streaming.kafka import KafkaUtils
    sc = SparkContext("local[*]", "stream")
    ssc = StreamingContext(sc, 1)

这给了我一个错误

Spark Streaming's Kafka libraries not found in class path. Try one 
    of the following.

    1. Include the Kafka library and its dependencies with in the
    spark-submit command as

    $ bin/spark-submit --packages org.apache.spark:spark-streaming- 
    kafka-0-8:2.3.2 ...

看来我需要把jar加到我的table上

!/usr/local/bin/spark-submit   --master local[*]  /usr/local/Cellar/apache-spark/2.3.0/libexec/jars/spark-streaming-kafka-0-8-assembly_2.11-2.3.2.jar pyspark-shell

它回来了

Error: No main class set in JAR; please specify one with --class
    Run with --help for usage help or --verbose for debug output

我上什么课？如何让Pypark连接到消费者？
