> Project: Flink
> Issue Type: Task
> Components: Documentation
> Reporter: Bowen Li

> Priority: Major
> Labels: pull-request-available
> Fix For: 1.10.0
>
>
> 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.
