I am trying to run a spark streaming application on Ubuntu, but I get some errors. For some reason Ubuntu 22.04 does not locate the jar files despite the fact the same configuration works on Windows.

I run the following configuration in a script

    spark = SparkSession \
        .builder \
        .appName("File Streaming PostgreSQL") \
        .master("local[3]") \
        .config("spark.streaming.stopGracefullyOnShutdown", "true") \
        .config("spark.jars.packages", "org.apache.spark:spark-avro_2.12:3.3.0,org.apache.spark:spark-sql-kafka-0-10_2.12:3.3.0") \
        .config("spark.sql.shuffle.partitions", 2) \
        .getOrCreate()

in addition to that, I download and locate all the jar files for avro and sql in /usr/local/spark/jars

• spark-sql-kafka-0-10_2.12-3.3.0.jar
• spark-sql-kafka-0-10_2.12-3.3.0-tests.jar
• spark-sql-kafka-0-10_2.12-3.3.0-javadoc.jar
• spark-sql-kafka-0-10_2.12-3.3.0-sources.jar
• spark-sql-kafka-0-10_2.12-3.3.0-test-sources.jar
• spark-avro_2.12-3.3.0.jar
• spark-avro_2.12-3.3.0-tests.jar
• spark-avro_2.12-3.3.0-javadoc.jar
• spark-avro_2.12-3.3.0-sources.jar
• spark-avro_2.12-3.3.0-test-sources.jar

my spark version is 3.3.0 and scala version is 2.12.14 and OpenJDK 64-Bit Server VM, Java 11.0.16, but I get the following error

This problem persists despite that I have the following configuration on .bashrc

#configuration for local Spark and Hadoop
SPARK_HOME=/usr/local/spark-3.3.0-bin-hadoop3
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin
export PYSPARK_PYTHON=/usr/bin/python3
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin

It is important to notice that everything works fine on Windows, and other applications that do not make use of SQL injection and avro serialization work just fine on Ubuntu 22.04 as well.

CodePudding user response：

You need kafka-clients.jar for the mentioned class.

You don't need Spark tests, sources or Javadoc in your Spark runtime.

Also, if you're trying to use Avro with a Schema Registry, then spark-avro isn't what you want.
