Subject [jira] [Commented] (HIVE-6167) Allow user-defined functions to be qualified with database name
Date Sun, 09 Mar 2014 06:24:47 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13925126#comment-13925126

Lefty Leverenz commented on HIVE-6167:
--------------------------------------

[~jdere] documented this in the wiki's DDL doc, so I added a brief description in the Hive
Plugins doc and linked it to the DDL.

* [DDL:  Permanent Functions |https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-PermanentFunctions]
* [Hive Plugins |https://cwiki.apache.org/confluence/display/Hive/HivePlugins]

But the jira description currently has things backwards:  "This task would allow users to
define temporary UDFs (and eventually permanent UDFs) with a database name" -- it's permanent
UDFs that can be defined with a database name, not temporary UDFs.

> Function names in Hive are currently unqualified and there is a single namespace for
all function names. This task would allow users to define temporary UDFs (and eventually permanent
UDFs) with a database name, such as:
> CREATE TEMPORARY FUNCTION userdb.myfunc 'myudfclass';
