Description

INSERT INTO Iceberg table is broken when we use INSERT events.

We get a NullPointerException for partitioned tables here:

https://github.com/apache/impala/blob/0c89a9cf0f2b642ca214e4fa68eeea9bc32ef3af/fe/src/main/java/org/apache/impala/service/CatalogOpExecutor.java#L4953

Repro:

create table test_ice (i int, p int) partition by spec (p bucket 5) stored as iceberg;
insert into test_ice values (1, 2);

Since Hive Replication doesn't work for Iceberg tables yet it's probably better to disable INSERT events for Iceberg tables.
