Addressed comments
Bugs: HIVE-7669
https://issues.apache.org/jira/browse/HIVE-7669
Repository: hive-git
Description
-------
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.
{code:sql}
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;
