### Change Logs Since Flink 1.17, Flink SQL support more advanced alter table syntax. ``` -- add a new column ALTER TABLE MyTable ADD category_id STRING COMMENT 'identifier of the category'; -- modify a column type, comment and position ALTER TABLE MyTable MODIFY measurement double COMMENT 'unit is bytes per second' AFTER `id`; -- drop columns ALTER TABLE MyTable DROP (col1, col2, col3); -- rename column ALTER TABLE MyTable RENAME request_body TO payload; ``` Find more detail information in [Flink Alter Table SQL ](https://nightlies.apache.org/flink/flink-docs-release-1.18/docs/dev/table/sql/alter/). We could support schema evolution by Flink SQL. This pr aims to support it based on `HoodieHiveCatalog`. Based on `HoodieCatalog` is not included in this pr, and would be in the later PR. ### Impact None ### Risk level (write none, low medium or high below) None ### Documentation Update None ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Change Logs and Impact were stated clearly - [ ] Adequate tests were added if applicable - [ ] CI passed -- This is an automated message from the Apache Git Service.
