Lefty Leverenz commented on HIVE-12182: --------------------------------------- Did this make any syntax changes? If so, it needs a TODOC1.3 label and a release note. Here's where the documentation should go: * [DDL -- Alter Column -- ChangeColumnName/Type/Position/Comment | https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ChangeColumnName/Type/Position/Comment] > ALTER TABLE PARTITION COLUMN does not set partition column comments > ------------------------------------------------------------------- > > Key: HIVE-12182 > URL: https://issues.apache.org/jira/browse/HIVE-12182 > Project: Hive > Issue Type: Bug > Components: SQL > Affects Versions: 1.2.1 > Reporter: Lenni Kuff > Assignee: Naveen Gangam > Fix For: 1.3.0, 2.0.0 > > Attachments: HIVE-12182-branch1.txt, HIVE-12182.2.patch, > HIVE-12182.3.patch, HIVE-12182.patch > > > ALTER TABLE PARTITION COLUMN does not set partition column comments.
