Deprecated.

TODO hack code, its logical should be integrated to TableSqlFunction

@Deprecated
public class HiveTableSqlFunction
extends org.apache.flink.table.planner.functions.utils.TableSqlFunction

Hive TableSqlFunction. Override getFunction to clone function and invoke HiveGenericUDTF#setArgumentTypesAndConstants. Override SqlReturnTypeInference to invoke HiveGenericUDTF#getHiveResultType instead of HiveGenericUDTF#getResultType(Object[], Class[]).
