UDFs to allow them to specify additional FILE/JAR resources necessary for
execution".
INLINE COMMENTS
ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java:1091 A file
handle is state. Or at least, I haven't seen a function that depended on
external files that wasn't stateful.
ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFInFile.java:41 Is
the test case not sufficient? You'll notice that the resource added is the
fully qualified path, but the file loaded is the unqualified path (since on
execution time you don't get the absolute path).

> 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.
