> When defining UDF functions in Hive it is possible to load the UDF jar(s) from a shared
location e.g. from hive.reloadable.aux.jars.path, and then use the CREATE FUNCTION statement:
> {{CREATE FUNCTION <your_function_name> AS '<fully_qualified_class_name>';}}
> These UDFs are not working from Spark unless you use the 
> {{CREATE FUNCTION <your_function_name> AS '<fully_qualified_class_name>'
USING JAR
>                   'hdfs:///<path/to/jar/in/hdfs>';}}
> command to create the Hive UDF function.
