INLINE COMMENTS
  ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFInFile.java:41 In what ways
would you expect differences to pop up?  Is there a way I can test these code paths easily
in my unittest?
  ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java:1091 Internal state such
as whether or not I've opened the file handle seem to me to be as stateful as a cumulative
sum?

> 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.
