-----------------------------
Description:
Consider the following scenario:
create table s1 as select * from src where key = 0;
set hive.auto.convert.join.noconditionaltask=false;
SELECT * FROM s1 src1 LEFT OUTER JOIN s1 src2 ON (src1.key = src2.key AND src2.key > 10);
gives correct results
0 val_0 NULL NULL
0 val_0 NULL NULL
0 val_0 NULL NULL
whereas it gives no results with hive.auto.convert.join.noconditionaltask set
to true
