> Note that Hive scalar and table functions implementing UDF, GenericUDF, and GenericUDTF interfaces should be good to run in both 
> streaming and batch mode in Flink.
> Due to that Hive functions are all built for batch processing, aggregate functions in Hive that implement UDAF and GenericUDAFResolver2 
> interfaces may have unpredictable behaviors when used in streaming mode in Flink. We advice users to only use Hive aggregate functions
> interfaces in batch mode.
