Venki Korukanti updated DRILL-3273:
-----------------------------------
Attachment: DRILL-3273-1.patch
We are passing null DeferredObject for argument whose value is null. This
causes NPE with UDFs that don't check for null before accessing the actual
argument value in DeferredObject. Fix is to pass a DeferredObject with null as
the argument value.
