Change subject: IMPALA-10166 (part 2): Enable DROP and CHANGE column ...................................................................... IMPALA-10166 (part 2): Enable DROP and CHANGE column IMPALA-10166 (part 1) already added the necessary code for DROP and CHANGE COLUMN, but disabled those stmts because to correctly support schema evolution we had to wait for column resolution by Iceberg field id. Since then IMPALA-10361 and IMPALA-10485 added support for field-id based column resolution for Parquet and ORC as well. Hence this patch enables DROP and CHANGE column ALTER TABLE statements. We still disallow REPLACE COLUMNS because it doesn't really make sense for Iceberg tables as it basically makes all existing data inaccessible.
