Bowen Li created FLINK-15593: -------------------------------- Summary: add doc to remind users not using Hive aggregate functions in streaming mode Key: FLINK-15593 URL: https://issues.apache.org/jira/browse/FLINK-15593 Project: Flink Issue Type: Task Components: Documentation Reporter: Bowen Li Assignee: Bowen Li 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
