    Description

      There are three tables in Hive metastore schema having COMMENT COLUMN: PARTITIION_KEYS, COLUMNS_V2, and TYPE_FIELDS, and their sizes are different. PARTITIION_KEYS.COMMENT has a size of 4000. To be consistent, and to make it more reasonable, we need to promote the column in other two tables from the current size (256) to 4000.
