We need to support custom UDFs that is available on SQL queries.
UDFs allow enabling new functions in SQL by abstracting their lower level language implementations. 
Spark SQL offers integrating custom udf easily.
I think it would be nice to provide an interface to register the custom UDFs in the Job Description.
