-----------------------------------

             Summary: Sorted by order of table not respected
                 Key: HIVE-3247
                 URL: https://issues.apache.org/jira/browse/HIVE-3247
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 0.10.0
            Reporter: Kevin Wilfong


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
97      val_97
98      val_98
98      val_98
