Apache Iceberg is an open-source table format for data stored in data lakes. It is optimized for data access patterns in Amazon Simple Storage Service (Amazon S3) cloud object storage. Iceberg helps data engineers tackle complex challenges in data lakes such as managing continuously evolving datasets while maintaining query performance. The Iceberg catalog The metadata layer, which contains metadata files, manifest lists, and manifest files The data layer Iceberg catalog Anyone reading from a table (let alone 10s, 100s, or 1,000s) needs to know where to go first — somewhere they can go to find out where to read/write data for a given table. The way org.apache.iceberg.spark.SparkSessionCatalog works is by first trying to load an iceberg table with the given identifier and then falling back the default catalog behaviour for this session catalog. Since you are using ice_test2 as your catalog it doesn't know which SessionCatalog to fallback to. To create an Iceberg table, you'll need a schema, a partition spec and a table identifier: Schema schema = new Schema ( required(1, "hotel_id", Types.LongType.get()), optional(2, "hotel_name",. Apache Iceberg in CDP : Our Approach. Iceberg provides a well defined open table format which can be plugged into many different platforms. It includes a catalog that supports atomic changes to snapshots – this is required to ensure that we know changes to an Iceberg table either succeeded or failed. Iceberg uses Apache Spark's DataSourceV2 API for data source and catalog implementations. Spark DSv2 is an evolving API with different levels of support in Spark versions. Spark 2.4 does not support SQL DDL. Spark 2.4 can't create Iceberg tables with DDL, instead use Spark 3.x or the Iceberg API . CREATE TABLE. Iceberg catalog In these processes, Iceberg opens up abstractions that allow developers to customize some of their functions, which is called the catalog in Iceberg. Figure 5. Catalog abstract functions These operations depend on the implementation of the storage tier, so the storage becomes an important option in this scenario. .

Cannot find catalog plugin class for catalog 'spark_catalog': org.apache.iceberg.spark.SparkSessionCatalog. Which means that the iceberg-spark3-runtime jar wasn't actually put on the classpath. I would check the startup log for the thrift server and make sure that the process was able to correctly connect to maven and get the required binaries.

Catalog implementations can be dynamically loaded in most compute engines. For Spark and Flink, you can specify the catalog-impl catalog property to load it. Read the Configuration section for more details. For MapReduce, implement org.apache.iceberg.mr.CatalogLoader and set Hadoop property iceberg.mr.catalog.loader.class to load it.
