Resolution: Duplicate

> SQL - Running query with outer join from 1.6 fails
> --------------------------------------------------
>
> Key: SPARK-17384
> URL: https://issues.apache.org/jira/browse/SPARK-17384
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Don Drake
> Assignee: Herman van Hovell
>
> I have some complex (10-table joins) SQL queries that utilize outer joins
> that work fine in Spark 1.6.2, but fail under Spark 2.0. I was able to
> duplicate the problem using a simple test case.
> Here's the code for Spark 2.0 that doesn't run (this runs fine in Spark
> 1.6.2):
> {code}
> case class C1(f1: String, f2: String, f3: String, f4: String)
> case class C2(g1: String, g2: String, g3: String, g4: String)
> case class C3(h1: String, h2: String, h3: String, h4: String)
> val sqlContext = spark.sqlContext
> val c1 = sc.parallelize(Seq(
> C1("h1", "c1a1", "c1b1", "c1c1"),
> C1("h2", "c1a2", "c1b2", "c1c2"),
> C1(null, "c1a3", "c1b3", "c1c3")
> )).toDF
> c1.createOrReplaceTempView("c1")
> val c2 = sc.parallelize(Seq(
> C2("h1", "c2a1", "c2b1", "c2c1"),
> C2("h2", "c2a2", "c2b2", "c2c2"),
> C2(null, "c2a3", "c2b3", "c2c3"),
> C2(null, "c2a4", "c2b4", "c2c4"),
> C2("h333", "c2a333", "c2b333", "c2c333")
> )).toDF
> c2.createOrReplaceTempView("c2")
> val c3 = sc.parallelize(Seq(
> C3("h1", "c3a1", "c3b1", "c3c1"),
> C3("h2", "c3a2", "c3b2", "c3c2"),
> C3(null, "c3a3", "c3b3", "c3c3")
> )).toDF
> c3.createOrReplaceTempView("c3")
> // doesn't work in Spark 2.0, works in Spark 1.6
> val bad_df = sqlContext.sql("""
> select *
> from c1, c3
> left outer join c2 on (c1.f1 = c2.g1)
> where c1.f1 = c3.h1
> """).show()
> // works in both
> val works_df = sqlContext.sql("""
> select *
> from c1
> left outer join c2 on (c1.f1 = c2.g1),
> c3
> where c1.f1 = c3.h1

> {code}
> Here's the output after running bad_df in Spark 2.0:
