CDPD-94256: Expand COMMENT column length in COLUMNS_V2 table: Previously, the COMMENT column in the HMS COLUMNS_V2 table was limited to 256 characters, which restricted customers from adding comprehensive context to Hive table columns.; This issue is resolved by expanding the COMMENT column to 4 KB to allow longer column descriptions. This enables customers to add detailed context to each column of their Hive tables for use by AI agents and other tools that generate SQL and reports based on column metadata.

If the backend database is MySQL and the COMMENT column does not use the latin1 character set, you must back up the COLUMNS_V2 table before upgrading. Otherwise, the COMMENT column data might become corrupted and cannot be reverted. In this case, you must modify the MySQL ALTER TABLE statement according to the active character set. For example, if the COMMENT column uses the UTF-8 character set, run the following commands:
ALTER TABLE COLUMNS_V2 MODIFY COLUMN COMMENT varchar(4000) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT NULL, ALGORITHM=COPY; -- Update the schema version UPDATE CDH_VERSION SET SCHEMA_VERSION='3.1.3000.7.3.2.0-Update2', VERSION_COMMENT='Hive release version 3.1.3000 for CDH 7.3.2.0-Update2' WHERE VER_ID=1;
