Spark #

It is necessary to modify the parameter spark.driver.extraClassPath in the console and add the path to the Spark jars, such as /usr/lib/emr/current/spark3/jars/* (please confirm that the path exists due to differences between versions). In addition, you need to add the relevant catalog parameters in spark-default.conf or use the set command (see Iceberg parameter configuration for details).

Flink #

It is necessary to copy the Iceberg dependencies to the nodes in the cluster.

cd /usr/lib/emr/current/flink 
-- Copy the dependencies required by Iceberg
cp /usr/lib/emr/current/iceberg/lib/iceberg-flink-runtime-*.jar  lib
