> 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")
