Kafka-pyspark Потоковая передача: KafkaException: не удалось построить потребитель kafka

/ 07 февраля 2020

Я пытаюсь подписаться на Kafka topi c через pyspark со следующим кодом: 

spark = SparkSession.builder.appName("Spark Structured Streaming from Kafka").getOrCreate()

lines = spark.readStream.format("kafka").option("kafka.bootstrap.servers", "localhost:9092").option("kafka.partition.assignment.strategy","range").option("subscribe", "test-events").load()

words = lines.select(explode(split(lines.value, " ")).alias("word"))

wordCounts = words.groupBy("word").count()

query = wordCounts.writeStream.outputMode("complete").format("console").start()

query.awaitTermination()

и использую следующую команду: 

spark-submit --packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.0 test_events.py

и версии для spark , kafka, java и scala: 

spark=2.4.0
kafka=2.12-2.3.0
scala=2.11.12
openJDK=1.8.0_221

Я продолжаю получать следующие ошибки: 

Current State: ACTIVE
Thread State: RUNNABLE

Logical Plan:
Aggregate [word#26], [word#26, count(1) AS count#30L]
+- Project [word#26]
   +- Generate explode(split(cast(value#8 as string),  )), false, [word#26]
      +- StreamingExecutionRelation KafkaV2[Subscribe[test-events]], [key#7, value#8, topic#9, partition#10, offset#11L, timestamp#12, timestampType#13]

During handling of the above exception, another exception occurred:

В Интернете есть несколько похожих вопросов, но ни один ответ мне не помог, поэтому далеко. Я также попробовал вышеупомянутое со свечой 2.4.4 со следующим: spark-submit --packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.4 test_events.py, но я продолжаю получать те же самые ошибки.

Решено с помощью:

Кафка версии 2.12-2.2.0

java .lang.ClassNotFoundException: range

Если вам явно не нужна стратегия назначения, удалите эту опцию.

В противном случае она должна быть полностью квалифицированный Java имя класса

Попробуйте изменить kafka.partition.assignment.strategy на roundrobin из диапазона и посмотрите, работает ли он. 

lines = spark.readStream.format("kafka").option("kafka.bootstrap.servers", "localhost:9092").option("kafka.partition.assignment.strategy","roundrobin").option("subscribe", "test-events").load()

Если это не сработает даже после этого, попробуйте добавить kafka-clients-0.10.0.1.jar при отправке задания зажигания. 

spark-submit --packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.0 --jars local:///root/sources/jars/kafka-clients-0.10.0.1.jar --driver-class-path local:///root/sources/jars/kafka-clients-0.10.0.1.jar test_events.py
