---------------------------------------
Good catch [~yalovyyi]! I've fixed that mistake and a few more in the DDL doc.
* [Alter Column -- ChangeColumnName/Type/Position/Comment |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ChangeColumnName/Type/Position/Comment]
* [Alter Column -- Add/ReplaceColumns |

The confusion about 0.15.0 and 1.1.0 is documented on the wiki home page:

> Affects Versions: 1.0.0
> Reporter: Illya Yalovyy
> Assignee: Lefty Leverenz

> Current documentation says that key word CASCADE was introduced in Hive 0.15
