Hi, IMO, 'org.apache.hadoop.hive.ql.lockmgr.DbTxnManager' is used for hive native acid table, not for Iceberg table. The lock mechanism in Iceberg table is controlled by HMS Catalog or other Iceberg Catalog(JDBC catalog, etc). So 'org.apache.hadoop.hive.ql.lockmgr.DbTxnManager' should not be used in your case(insert overwrite iceberg table).
