Spark Structured Streaming with PySpark throwing error in execution

[Mich Talebzadeh]

Hi,

Trying to make PySpark with PyCharm work with Structured Streaming

spark-3.0.1-bin-hadoop3.2

kafka_2.12-1.1.0

Basic code

from __future__ import print_function

from src.config import config, hive_url

from sparkutils import sparkstuff as s

class MDStreaming:

        self.spark = spark_session

        self.sc = spark_context

        self.config = config

    def startStreaming(self):

        self.sc.setLogLevel("ERROR")

        try:

            kafkaReaderWithHeaders = self.spark \

                .readStream \

                .format("kafka") \

                sys.exit(1)

        kafkaReaderWithHeaders.selectExpr("CAST(key AS STRING)", "CAST(value AS STRING)", "headers") \

            .writeStream \

You should include commons-pool2-2.9.0.jar and remove spark-streaming-kafka-0-10_2.12-3.0.1.jar (unnecessary jar).

Appreciate any feedback.

Hi all,

Following the upgrade to 3.1.1, I see a couple of issues.

Spark Structured Streaming (SSS) does not seem to work with the newer spark-sql-kafka-0-10_2.12-3.1.1.jar for Spark. It throws 

java.lang.NoSuchMethodError: org.apache.spark.kafka010.KafkaTokenUtil$.needTokenUpdate(Ljava/util/Map;Lscala/Option;)Z

So I have to use the previous jar file spark-sql-kafka-0-10_2.12-3.0.1.jar 

However, we can set aside that for now

The second point is that with the following jars under $SPARK_HOME/jars

1. spark-sql-kafka-0-10_2.12-3.0.1.jar
2. commons-pool2-2.9.0.jar
3. kafka-clients-2.7.0.jar

The SSS job runs in local mode as a single JVM

In Yarn mode this fails with the following error

java.lang.NoClassDefFoundError: Could not initialize class org.apache.spark.sql.kafka010.consumer.KafkaDataConsumer

Even other executors running on the same node fail as well. with the above error.

I have ensured that those jar files are available on all three nodes of the cluster (on-prem)  but still no luck,

Any ideas appreciated.

Thanks

I have used the following jars in $SYBASE_HOME/jars

  spark-sql-kafka-0-10_2.12-3.0.1.jar

 kafka-clients-2.7.0.jar

 spark-streaming-kafka-0-10_2.12-3.0.1.jar

 spark-token-provider-kafka-0-10_2.12-3.0.1.jar

and also in $SPARK_HOME/conf/spark-defaults.conf

spark.driver.extraClassPath        $SPARK_HOME/jars/*.jar

spark.executor.extraClassPath      $SPARK_HOME/jars/*.jar

The error is this:

The thing is that the class is in the jar file below in $SPARK_HOME/jars

find $SPARK_HOME/jars/  -name "*.jar" | xargs grep org.apache.spark.sql.kafka010.consumer.KafkaDataConsumer

Binary file jars/spark-sql-kafka-0-10_2.12-3.0.1.jar matches

Appreciate any feedback.

Thanks
