Description

Setup:

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;  

Query:

 select * from tst_dest30; 

Expected Result:

 10 

Actual Result:

 500 

Turning on hive test mode is suppose to generate sampling (implicit tablesample clause) but return path isn't honoring hive.test.mode flag
