IMPALA-10368: Support required/optional property when creating Iceberg table
We supported create required/optional field for Iceberg table in this
patch. If we set 'NOT NULL' property for Iceberg table column in SQL,
Impala will create required field by Iceberg api, 'NULL' or default
will create optional field.
Besides, 'DESCRIBE XXX' for Iceberg table will display 'optional'
property like this:
+------+--------+---------+----------+
| name | type | comment | nullable |
+------+--------+---------+----------+
| id | int | | false |
| name | string | | true |
| age | int | | true |
+------+--------+---------+----------+
And 'SHOW CREATE TABLE XXX' will also display 'NULL'/'NOT NULL'
property for Iceberg table.
Tests:
* added new test in iceberg-create.test
* added new test in iceberg-negative.test
* added new test in show-create-table.test
* modify 'DESCRIBE XXX' result in iceberg-create.test
* modify 'DESCRIBE XXX' result in iceberg-alter.test
* modify create table result in show-create-table.test
