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

             Summary: parallel order by clause on a string column fails with IOException: Split points are out of order
                 Key: HIVE-7669
                 URL: https://issues.apache.org/jira/browse/HIVE-7669
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2, Query Processor, SQL
    Affects Versions: 0.12.0
         Environment: Hive 0.12.0-cdh5.0.0
OS: Redhat linux
            Reporter: Vishal Kamath


The source table has 600 Million rows and it has a String column "l_shipinstruct" which has 4 unique values. (Ie. these 4 values are repeated across the 600 million rows)

We are sorting it based on this string column "l_shipinstruct" as shown in the below HiveQL with the following parameters. 

set hive.optimize.sampling.orderby=true;
set hive.optimize.sampling.orderby.number=10000000;
set hive.optimize.sampling.orderby.percent=0.1f;

insert overwrite table lineitem_temp_report 
select 
  l_orderkey, l_partkey, l_suppkey, l_linenumber, l_quantity, l_extendedprice, l_discount, l_tax, l_returnflag, l_linestatus, l_shipdate, l_commitdate, l_receiptdate, l_shipinstruct, l_shipmode, l_comment
from 
  lineitem
order by l_shipinstruct;
