URL: https://issues.apache.org/jira/browse/HIVE-3247
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.10.0

When a table a sorted by a column or columns, and data is inserted with
hive.enforce.sorting=true, regardless of whether the metadata says the table is
sorted in ascending or descending order, the data will be sorted in ascending
order.
e.g.
create table table_desc(key string, value string) clustered by (key) sorted by
(key DESC) into 1 BUCKETS;
create table table_asc(key string, value string) clustered by (key) sorted by
(key ASC) into 1 BUCKETS;
insert overwrite table table_desc select key, value from src;
insert overwrite table table_asc select key, value from src;
select * from table_desc;
...
96 val_96
97 val_97
97 val_97
98 val_98
98 val_98
select * from table_asc;
...
96 val_96
97 val_97
