GCP dataproc - java.lang.NoClassDefFoundError: org/apache/kafka/common/serialization/ByteArraySerializer

Question

i'm trying to run a StructuredStreaming job on GCP DataProc, which reads from Kafka nd prints out the values. The code is giving error -> java.lang.NoClassDefFoundError: org/apache/kafka/common/serialization/ByteArraySerializer

Here is the code:

import sys, datetime, time, os
from pyspark.sql.functions import col, rank, dense_rank, to_date, to_timestamp, format_number, row_number, lead, lag,monotonically_increasing_id
from pyspark.sql import SparkSession, Window
from confluent_kafka import Producer
from google.cloud import storage

spark = SparkSession.builder.appName('StructuredStreaming_VersaSase').getOrCreate()

spark.sparkContext.setLogLevel("ERROR")

kafkaBrokers='34.75.148.41:9094'
topic = "versa-sase"
# bootstrap.servers=my-cluster-lb-ssl-cert-kafka-bootstrap:9093
security_protocol="SSL"


client = storage.Client()
print(" client ", client)

bucket = client.get_bucket('ssl-certs-karan')
print(" bucket ", bucket)

allblobs = bucket.list_blobs()
print(" allblobs -> ", allblobs)

for b in allblobs:
    print(" b -> ", b)

blob_ssl_truststore_location = bucket.get_blob('ca.p12')
print(" blob_ssl_truststore_location.name ", blob_ssl_truststore_location.name)
blob_ssl_truststore_location.download_to_filename(blob_ssl_truststore_location.name)

ssl_truststore_location=blob_ssl_truststore_location.name
print(" type - blob_ssl_truststore_location ", type(blob_ssl_truststore_location))
ssl_truststore_password="NAvqbh5c9fB4"

blob_ssl_keystore_location = bucket.get_blob('dataproc-versa-sase.p12')
print(" blob_ssl_keystore_location.name ", blob_ssl_keystore_location.name)
blob_ssl_keystore_location.download_to_filename(blob_ssl_keystore_location.name)
ssl_keystore_location=blob_ssl_keystore_location.name
ssl_keystore_password="jBGsWrBv7258"
consumerGroupId = "versa-sase-grp"
checkpoint = "gs://ss-checkpoint/"

print(" SPARK.SPARKCONTEXT -> ", spark.sparkContext)



df = spark.read.format('kafka')\
    .option("kafka.bootstrap.servers",kafkaBrokers)\
    .option("kafka.security.protocol","SSL") \
    .option("kafka.ssl.truststore.location",ssl_truststore_location) \
    .option("kafka.ssl.truststore.password",ssl_truststore_password) \
    .option("kafka.ssl.keystore.location", ssl_keystore_location)\
    .option("kafka.ssl.keystore.password", ssl_keystore_password)\
    .option("subscribe", topic) \
    .option("kafka.group.id", consumerGroupId)\
    .option("startingOffsets", "earliest") \
    .load()
#


query = df.selectExpr("CAST(value AS STRING)") \
    .write \
    .format("console") \
    .option("numRows",100)\
    .option("checkpointLocation", checkpoint) \
    .option("outputMode", "complete")\
    .save("output")

# query.awaitTermination()

Command to launch the job on Dataproc cluster :

gcloud dataproc jobs submit pyspark \
StructuredStreaming_Kafka_GCP-Batch-feb1.py --cluster=dataproc-ss-poc 
--jars=gs://spark-jars-karan/spark-sql-kafka-0-10_2.12-3.1.2.jar

I've checked the Spark version on the Dataproc cluster, and spark version - 3.1.2,and scala version - 2.12 .. so the version of the spark-sql jar being passed seems to be correct. Are there any other jars to be passed ?

What needs to be done to fix/debug this issue ?

tia !

Answer 1

The missing class org/apache/kafka/common/serialization/ByteArraySerializer is in the kafka-clients package 1 which is a dependency of the spark-sql-kafka-0-10_2.12 package 2.

You can use either --packages org.apache.spark:spark-sql-kafka-0-10_2.12:3.2.1 which automatically pulls the transitive dependencies, or --jars=gs://my-bucket/spark-sql-kafka-0-10_2.12-3.1.2.jar,gs://my-bucket/kafka-clients-0.10.2.2.jar to add all the dependencies.

Answer 2

i was able to resolve this issue, by passing the package as below i.e. --properties spark.jars.packages=org.apache.spark:spark-sql-kafka-0-10_2.12:3.1.2 Pls note : i also added the individual jars initially to resolve the issue, however that clearly is not the right way

gcloud dataproc jobs submit pyspark /Users/karanalang/Documents/Technology/gcp/DataProc/StructuredStreaming_Kafka_GCP-Batch-feb2.py  --cluster dataproc-ss-poc  --properties spark.jars.packages=org.apache.spark:spark-sql-kafka-0-10_2.12:3.1.2 --region us-central1
