set hive.tez.bucket.pruning=true; 


CREATE TABLE `test_table`(                 
   `col_1` int,                                     
   `col_2` string,                                  
   `col_3` string)                                  
 CLUSTERED BY (                                     
   col_1)                                           
 INTO 4 BUCKETS;                                     

insert into test_table values(1, 'one', 'ONE'), (2, 'two', 'TWO'), (3,'three','THREE'),(4,'four','FOUR');

select * from test_table;

explain select col_1, col_2, col_3 from test_table where col_1 <> 2 order by col_2;
select col_1, col_2, col_3 from test_table where col_1 <> 2 order by col_2;

Above sql query produce zero rows.
