Rui Li commented on FLINK-22827:
--------------------------------
Hi [~aidenma], currently Flink doesn't support the semantics of bucketed/sorted
hive tables. So even if the DDL allows you to create such a table, you probably
won't get the desired behavior when writing to this table with Flink, e.g. the
data won't be shuffled/sorted according to the bucket/sort key you specified.
> Hive dialect supports CLUSTERED BY clause of CREATE TABLE DDL
