Hi there Docs claim: Currently, Hive UDFs that accept or return the TIMESTAMP type are not supported.
Acceptable types in the source code: https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/hive/executor/UdfExecutor.java#L143 What is the reason behind the scene? Why this functionality is supported for C++ binding, but not for Java? Is there any tech issues related to this topic? I want to implement several UDF helpers/aliases/shortcuts to get time in different time zones. Regards, Eugen
