MERGE INTO TABLE is not supported temporarily.

i’m trying to execute a Merge operation between 2 iceberg tables and it seems i get the following error:

The setup is the following:

        <scala.version>2.12.0</scala.version>
        <spark.version>3.0.2</spark.version>
        <iceberg.version>0.11.1</iceberg.version>
        <hadoop.version>3.1.1</hadoop.version>
        <druid.version>1.1.21</druid.version>
        <kafka.version>2.0.0</kafka.version>
        <hive.version>3.1.1</hive.version>

    val spark = SparkSession
      .builder()
      .master("local[2]")
      .appName("IcebergAPI")
      .config("spark.sql.extensions", "org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions")
      .config("spark.sql.catalog.spark_catalog", "org.apache.iceberg.spark.SparkSessionCatalog")
      .config("spark.sql.catalog.spark_catalog.type", "hive")
      .config("spark.sql.catalog.hive_prod", "org.apache.iceberg.spark.SparkCatalog")
      .config("spark.sql.catalog.hive_prod.type", "hive")
      .config("spark.sql.catalog.hive_prod.warehouse", "hdfs://ambari5:8020/warehouse/tablespace/managed/hive")
      .config("spark.sql.catalog.hive_prod.uri", "thrift://ambari6:9083")
      .config("iceberg.engine.hive.enabled", "true")
      .enableHiveSupport()
      .getOrCreate()

now i can execute following sql susseccful only merge failed

spark.sql("create database if not exists hive_prod.ods2")
spark.sql("CREATE TABLE IF NOT EXISTS hive_prod.ods.table4 (id bigint, data string) USING iceberg")
spark.sql("INSERT INTO hive_prod.ods.table4 VALUES (1, 'aa'), (2, 'bb'), (3, 'cc')")
spark.sql("select * from  hive_prod.ods.table4").show()

Do you have any idea why it’s acting like this?
