    [ https://issues.apache.org/jira/browse/HIVE-16158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15904268#comment-15904268

Lefty Leverenz commented on HIVE-16158:
---------------------------------------

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 | https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Add/ReplaceColumns]
* [Describe Database | https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-DescribeDatabase]

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

* [Home -- Hive Versions and Branches | https://cwiki.apache.org/confluence/display/Hive/Home#Home-HiveVersionsandBranches]

> Current documentation says that key word CASCADE was introduced in Hive 0.15 release.
That information is incorrect and confuses users. The feature was actually released in Hive
1.1.0. (HIVE-8839)
