Review Comment:
@zratkai you have created the ticket
[HIVE-28587](https://issues.apache.org/jira/browse/HIVE-28587), which means
that you will implement the `alter table `syntax like spark syntax.
https://iceberg.apache.org/docs/1.7.0/spark-ddl/#alter-table-write-ordered-by
Right?
> This syntax comes from the official Iceberg recommendation, which is for
alter table, and to be consistend I modified the ALTER to CREATE in the syntax,
so at CREATE table it is the same as ALTER TABLE:
I already know why you give this create syntax. But since there is no
uniform `Create `syntax for the `write order`, i think we no need to make
`Create `syntax to be consistend with the `Alter `syntax. If the table property
is more simple, i prefer to `create + table property` like trino.
If you think `create + table property` is also not friendly to users. I am
not against the currrent implementation. You just need to update the wiki doc
to tell users the create dialect for iceberg write order.
