Mark Grover commented on HIVE-2693:
-----------------------------------
I figured out why CAST(3.4 as DECIMAL) doesn't work as expected. It's because
there is a no UDF equivalent to UDFToDouble (we should call it UDFToDecimal)
that would do the cast from double to decimal. The associated implicit costs of
conversions need to be updated in FunctionRegistry as well for the newly
introduced decimal type. I am working on a patch. Will keep you posted!
