java.lang.ClassNotFoundException: org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions - using spark structured streaming
See original GitHub issueApache Iceberg version
1.0.0 (latest release)
Query engine
Spark
Please describe the bug 🐞
Application:
We are trying to use spark structured streaming in combination with iceberg. The application is containerised and behind the scenes running on EKS. Spark structured streaming worked well until we tried to add the iceberg extension. We have used iceberg successfully before in a local spark session before (not structured streaming).
Environment We have tried with the following versions:
Iceberg version: 1.0.0 ; 0.14.1 ; 0.13.1 Spark version: 3.2.0 ; 3.0.3 AWS SDK version: 2.17.257 ; 2.18.22 Scala version: 2.12
Extra configuration included into the spark session:
` REMOTE_CATALOG_NAME: str = “remote_glue_catalog”
config.setAll( [ ( “spark.jars.packages”, “org.apache.iceberg:iceberg-spark-runtime-3.0_2.12:0.14.1”, ), (“spark.jars.packages”, “software.amazon.awssdk:bundle:2.17.257”), ( “spark.jars.packages”, “software.amazon.awssdk:url-connection-client:2.17.257”, ), ( f"spark.sql.catalog.{REMOTE_CATALOG_NAME}“, “org.apache.iceberg.spark.SparkCatalog”, ), ( f"spark.sql.catalog.{REMOTE_CATALOG_NAME}.warehouse”, f"{aws.datalake_root_path()}/{table_name}/“, ), ( f"spark.sql.catalog.{REMOTE_CATALOG_NAME}.catalog-impl”, “org.apache.iceberg.aws.glue.GlueCatalog”, ), ( f"spark.sql.catalog.{REMOTE_CATALOG_NAME}.io-impl", “org.apache.iceberg.aws.s3.S3FileIO”, ), ( “spark.sql.extensions”, “org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions”, ), (f"spark.sql.defaultCatalog", REMOTE_CATALOG_NAME), ] )`

Debug checks:
- We have checked the docker container if the jars are included.
- We checked the spark config at runtime (logged) to make sure all options were included which they were
- Checked several version of spark + iceberg
Question So anybody know what is going on? My guess is that with spark structured streaming the jars aren’t really added to the classpath for the different executors but not sure.
Thanks in advance!

Update: I fixed it, I had a mistake in my docker container where I used
wget ... -o ...
This did write a jar but it was empty, I fixed it by using curl. Stupid mistake on my end, thanks for the help anyway.@RussellSpitzer I did, and I saw they were there, only once, and thus no different versions. I did use the same docker and envirnment for a batch job, and it is not working either. So I must be doing something wrong or different. When I find something I will update.
