Lefty Leverenz commented on HIVE-9357:
--------------------------------------
Doc note: This should be documented in the Date Functions section of the UDFs
wikidoc (with version information and a link to this issue).
* [Hive Operators and UDFs -- Date Functions |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions]
A release note would also be helpful. Does the description show the committed
functionality, or was it modified after the discussion?
