Spark 4.0.0-preview1 findings

[maltesander]

I tried to include the spark 4.0.0-preview1 image into 24.7.

While the build worked fine using these settings:

    {
        "product": "4.0.0-preview1",
        "java-base": "17",
        "java-devel": "17",
        "python": "3.11",
        "hadoop_long_version": "3.4.0",  # https://github.com/apache/spark/blob/7a7a8bc4bab591ac8b98b2630b38c57adf619b82/pom.xml#L125
        # NOTE: The "aws_java_sdk_bundle" jar now is only called bundle-x.x.x instead of aws-java-sdk-bundle-x.x.x and was renamed before uploading to nexus
        "aws_java_sdk_bundle": "2.23.19",  # https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-aws/3.4.0
        "azure_storage": "7.0.1",  # https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-azure/3.4.0
        "azure_keyvault_core": "1.0.0",  # https://mvnrepository.com/artifact/com.microsoft.azure/azure-storage/7.0.1
        "jackson_dataformat_xml": "2.17.1",  # https://mvnrepository.com/artifact/org.apache.spark/spark-core_2.13/4.0.0-preview1
        "stax2_api": "4.2.2",  # https://mvnrepository.com/artifact/com.fasterxml.jackson.dataformat/jackson-dataformat-xml/2.17.1
        "woodstox_core": "6.6.2",  # https://mvnrepository.com/artifact/com.fasterxml.jackson.dataformat/jackson-dataformat-xml/2.17.1
        "vector": "0.39.0",
        "jmx_exporter": "1.0.1",
        "tini": "0.19.0",
    },

I got some integration test failures and we decided to not include it in the 24.7 release.

Iceberg was e.g related when looking for an iceberg jar that simply does not exist yet.

This is just for future reference and nothing to act on for now.
