> Reporter: Zoltán Borók-Nagy

> Dropping column that participated in partitioning in the past corrupts table.
> {noformat}
> create table ice_part (i int, p int)
> partitioned by spec (bucket(7, p))
> stored by iceberg;
> insert into ice_part values (1,1);
> -- switch partitioning to other column
> alter table ice_part set partition spec (bucket(7, i));
> alter table ice_part drop column p;
> {noformat}
> The above generates a NullPointerException. Iceberg V2 tables work a bit
> differently when we change partitioning, but we still get an exception
> (TProtocolException: Required field 'orig_field_name' was not present!).
