Description

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):

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
""").show()

Here's the output after running bad_df in Spark 2.0:

scala> val bad_df = sqlContext.sql("""
     |   select *
     |   from c1, c3
     |   left outer join c2 on (c1.f1 = c2.g1)
     |   where c1.f1 = c3.h1
     | """).show()

I confirmed this fails on the Spark 2.0 nightly build as well. This runs just fine in Spark 1.6.2.
