      Description

      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.
