Phabricator commented on HIVE-2561:
-----------------------------------
atfiore has commented on the revision "HIVE-2561 [jira] Add an annotation to
UDFs to allow them to specify additional FILE/JAR resources necessary for
execution".
One inline comment below and one more general question: Will this
functionality be available only to GenericUDFs? It would be great to have this
for simple UDFs, too.
INLINE COMMENTS
ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDF.java:133 Is
"fully qualified path" really what we mean here? The examples in udf_in_file.q
use relative file paths.
And what about the case of fixed files/JARs required for the UDF to work and
distributed with it? Including fully qualified file paths seems brittle for
this use case. Or are the paths meant to be relative to some central,
configurable $root that all UDF-evaluation contexts can see?

> 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.
