Below is the code
from pyspark.sql import SparkSession
spark = SparkSession.builder.appName("Test").getOrCreate()
df = spark.readStream.format("kafka").option("kafka.bootstrap.servers",
“myserver:9092").option("subscribe", “my_topic").load()
By the way, I have the same Scala code is running with spark-shell by
adding "--packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.0”
Thank you
