[jira] [Created] (HIVE-2537) Disallow useless DISTRIBUTE BY/SORT BY/CLUSTER BY in strict mode

Disallow useless DISTRIBUTE BY/SORT BY/CLUSTER BY in strict mode
----------------------------------------------------------------

                 Key: HIVE-2537
                 URL: https://issues.apache.org/jira/browse/HIVE-2537
             Project: Hive
          Issue Type: Improvement
            Reporter: Adam Kramer
            Priority: Minor


This query:

CREATE TABLE my_tablename AS
SELECT a, b, c
FROM somewhere
CLUSTER BY c;

...has an unnecessary CLUSTER BY, because the resulting data will be loaded into a non-bucketed table without any enforcement of bucketing. We should disallow this in strict mode.
