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

             Summary: bug with hive.auto.convert.join.noconditionaltask with outer joins
                 Key: HIVE-4146
                 URL: https://issues.apache.org/jira/browse/HIVE-4146
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Namit Jain


Consider the following scenario:

create table s2 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
