Miklos Szurap commented on HIVE-15272:
--------------------------------------
As the amount field is a DECIMAL, it is very likely that HIVE-12768 is the root
cause.
> "LEFT OUTER JOIN" Is not populating correct 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
> Assignee: Rui Li
>
> I ran following Hive query multiple times with execution engine as Hive on
> Spark and Hive on MapReduce.
> {code}
> SELECT COUNT(DISTINCT t1.region, t1.amount)
> FROM my_db.my_table1 t1
> LEFT OUTER
> JOIN my_db.my_table2 t2 ON (t1.id = t2.id
> AND t1.name = t2.name)
> {code}
> With Hive on Spark: Result (count) were different of every execution.
> With Hive on MapReduce: Result (count) were same of every execution.
> Seems like Hive on Spark behaving differently in each execution and does not
> populating correct result.
