----------------------------------
Summary: CBO: Calcite Operator To Hive Operator(Calcite Return Path): Fix wrong result in input30
Key: HIVE-14610
URL: https://issues.apache.org/jira/browse/HIVE-14610
Project: Hive
Issue Type: Sub-task
Components: CBO
Reporter: Vineet Garg
Assignee: Vineet Garg
Setup:
{code}
set hive.mapred.mode=nonstrict;
create table dest30(a int);
create table tst_dest30(a int);
set hive.test.mode=true;
set hive.test.mode.prefix=tst_;
insert overwrite table dest30
select count(1) from src;
{code}
Query:
{code} select * from tst_dest30; {code}
Expected Result:
{code} 10 {code}
Actual Result:
{code} 500 {code}
Turning on hive test mode is suppose to generate sampling (implicit tablesample clause) but return path isn't honoring hive.test.mode flag
