python - 如何摆脱 Spark Streaming + Kafka 中的 NoSuchMethodError : org. apache.kafka.clients.consumer.KafkaConsumer.subscribe 错误

Question

我想使用 Spark Streaming 并将其与 Kafka 连接。但是我仍然收到 NoSuchMethodError: org.apache.kafka.clients.consumer.KafkaConsumer.subscribe 错误，现在我不知道下一步该怎么做。

我的设置:

Ubuntu 16.04

斯卡拉2.11

Kafka 2.11-1.0.0(我也尝试过使用2.11-0.10.0.0)

Spark 2.2.1

Hadoop 2.9.0

我什至无法运行示例脚本:

from pyspark.sql import SparkSession, Row, SQLContext
from pyspark import SparkContext, SparkConf
from pyspark.streaming import StreamingContext
from pyspark.streaming.kafka import KafkaUtils
from pyspark.sql.types import *

sparkSession = SparkSession.builder.appName("example-pyspark-read-and-write").getOrCreate() 

# Subscribe to 1 topic
df = sparkSession\
  .readStream\
  .format("kafka")\
  .option("kafka.bootstrap.servers", "localhost:9092")\
  .option("kafka.partition.assignment.strategy", "range") \
  .option("subscribe", "test")\
  .option("startingOffsets", "earliest")\
  .load() 

query = df.writeStream\
    .format("console")\
    .start()

query.awaitTermination()

我使用 Spark 在 Spark 上运行它

spark-submit --master local[2] --jars /home/some_path/spark-sql-kafka-0-10_2.11-2.2.1.jar spark_streaming_kafka_example.py 

我收到一个错误

我还尝试将spark-streaming-kafka-0-10- assembly_2.11-2.2.1包含在--jars中(而不是spark-sql-kafka-0-10_2.11-2.2.1.jar )，但也没有帮助。

我还尝试将这两行放入spark-defaults.conf

spark.driver.extraClassPath /home/some_path/spark-streaming-kafka-0-10-assembly_2.11-2.2.1.jar
spark.executor.extraClassPath /home/some_path/spark-streaming-kafka-0-10-assembly_2.11-2.2.1.jar

或者

spark.driver.extraClassPath /home/some_path/spark-sql-kafka-0-10_2.11-2.2.1.jar
spark.executor.extraClassPath /home/some_path/spark-sql-kafka-0-10_2.11-2.2.1.jar

尝试在 spark2-submit 命令之前运行 export SPARK_KAFKA_VERSION=0.10 。 [Source for solution]
