   i don't think Spark libraries is  conflict，and demo is from http://iceberg.apache.org/spark-writes/#merge-into
   
   I have already run : use zdm to V2 , and i can use insert/overwrite, but merge and call is error.
   
   I thought SQL Extensions was wrong,It didn't load successfully, but i look yarn-ui-application-Environment- Spark Properties-spark.sql.extensions is org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions。it's load successfully。
   
   阿西吧~
