Subject [jira] [Commented] (HIVE-2561) Allow UDFs to specify additional FILE/JAR resources necessary for execution
Date Mon, 21 Nov 2011 23:31:40 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13154727#comment-13154727
] 

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

A dependency declaration allows the resources to be automatically loaded so the end user doesn't
have to.  I don't think this is a niche case; this has come up a lot and this diff is the
result of a brainstorm in response to user complaints.

> 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.
