Subject [jira] [Commented] (HIVE-2561) Add an annotation to UDFs to allow them to specify additional FILE/JAR resources necessary for execution
Date Wed, 09 Nov 2011 00:21:51 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13146680#comment-13146680
] 

Jonathan Chang commented on HIVE-2561:
--------------------------------------

Hm, how would you feel about something more general then, like a method on the class that
would be called.  That method could potentially access things like environment vars, config
settings, etc. to dynamically specify the dependencies?

> Often times UDFs will have dependencies to external JARs/FILEs.  It makes sense for these
to be encoded by the UDF (rather than having the caller remember the set of files that need
to be ADDed).  Let's add an annotation to UDFs which will cause these resources to be auto-added.
