There are a couple of scenarios where the Hive DDL command
DROP TABLEcan produce an error unnecessarily.FileNotFoundExceptionexception, because based on Hive2/Hive3 behaviour, the current assumption is that theHiveIcebergMetaHookhas to clean up the metadata files after the Hive drop table has completed. However, in Hive4, ifexternal.table.purge=TRUEis set, Hive will wipe the metadata folder as well.Extended some of the unit tests with explicit DROP TABLE commands in the end to test for the whole flow of CREATE, INSERT, DROP (which currently triggers problem # 1 on Hive4).
