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

             Summary: "LEFT OUTER JOIN" Is not populating different records with Hive On Spark
                 Key: HIVE-15272
                 URL: https://issues.apache.org/jira/browse/HIVE-15272
             Project: Hive
          Issue Type: Bug
          Components: Hive, Spark
    Affects Versions: 1.1.0
         Environment: Hive 1.1.0, CentOS, Cloudera 5.7.4
            Reporter: Vikash Pareek


Following query is populating different result every time I ran with Hive on Spark:
"
SELECT COUNT(*)
FROM
  (SELECT DISTINCT mt1.name,
                   mt1.id
   FROM
     (SELECT mt1.*,
             mt2.region,
             mt2.,
             regexp_replace(mt2.tr_dat,"\\.","") AS TRANSACTION_DATE
      FROM my_database.my_table1 mt1
      LEFT OUTER JOIN my_database.my_table2 mt2 ON (mt1.id=mt2.id
                                                    AND mt1.name = mt2.name))t6)A;
"

But the same query populating same result with Hive on MapReduce every time.
