Subject [jira] Commented: (HIVE-309) FunctionRegistry should allow loading UDFs and UDAFs from property file
Date Wed, 01 Apr 2009 16:27:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694607#action_12694607
] 

Namit Jain commented on HIVE-309:
---------------------------------

However, if a client has some particular UDF implementation, and wants to use that, he will
be forced to add it to the server classpath
if we go with the metastore approach.

Will clients be able to add jar files to the server where the Hive server is running ?

> FunctionRegistry.java hard code all UDF, UDAF definitions in a static initializer.  There
is no way to add new functions without directly modifying this file.  
> FunctionRegistry SHOULD look for a property file in which new functions and their implementations
can be specified.  This will allow third parties to extend hive without maintaining patches
against the codebase.
