Hi @twalthr @JingsongLi , please help review this PR. I have incorporated the feedbacks in #13144 here. Regarding `getExpectedSignatures` for hive functions, unfortunately hive doesn't have an API to retrieve valid signatures for a function. Currently we use arguments to initialize the hive function, and if the arguments are invalid, a `UDFArgumentException` is thrown. But there's no way to get the expected signatures. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
