I know nothing about how to use iceberg v2 tables but I have tried the
following 3 steps in Impala shell. It seems Impala at the moment does not
support modifying a non-Kudu table yet.
1. create table test_db.iceberg_v2_parq (id int, user string)
STORED BY ICEBERG
location
'/test-warehouse/iceberg_test/hadoop_catalog/ice/iceberg_v2_partitioned_position_deletes'
tblproperties ('format-version'='2', 'write.format.default'='parquet');
2. insert into test_db.iceberg_v2_parq values (1, "Alex");
3. delete from test_db.iceberg_v2_parq where id = 1;
I encountered the following error after executing the delete statement.

ERROR: AnalysisException: Impala does not support modifying a non-Kudu table:
test_db.iceberg_v2_parq
On the other hand, I was not able to use Hive to perform the following steps
due to the missing class of HiveIcebergInputFormat.
1. In Impala shell:
create table test_db.iceberg_v2_orc (id int, user string)
STORED BY ICEBERG
location
'/test-warehouse/iceberg_test/hadoop_catalog/ice/iceberg_v2_partitioned_position_deletes'
tblproperties ('format-version'='2', 'write.format.default'='orc');
2. In beeline:
insert into test_db.iceberg_v2_orc values (1, "Alex");
I encountered the following error message.
Caused by: java.lang.ClassNotFoundException:
org.apache.iceberg.mr.hive.HiveIcebergInputFormat
