Subject [jira] [Commented] (HIVE-6167) Allow user-defined functions to be qualified with database name
Date Wed, 12 Feb 2014 00:32:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13898552#comment-13898552

Ashutosh Chauhan commented on HIVE-6167:
----------------------------------------

Patch looks good. I have one question tho. Earlier, function names were identifier. I assume
DOT can be part of an identifier. If so, than can it be a problem now if some one who has
earlier created a function name with dot in it, may now confuse Hive.

> 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';
